23 and Beckham

This is the first post of 2023. It feels like 2022 went by so fast. And I didn't realize that number 22 already had to be put away and tied by number 23. Anyway, I've always liked number 23, not for one reason but for various reasons that I was confused to explain.

23 became my favorite number when I first loved and followed football. That was when I used to play FIFA on my computer and lose track of time. Manchester United was my favorite club in the game, and David Beckham was my favorite player. At that time, Beckham moved to Real Madrid and became the most expensive player in the world. I was a bit disappointed, but I still followed Becks at Real Madrid. He wore the number 23 jersey, which is how I first came to love the number.

For me, Beckham is a player who not only relies on skill but also on intelligence in analyzing the match. The passes he gives to his teammates always show that he is a player with good vision. His passing technique and accuracy can also be considered high for a professional player. I even imitated the way he kicked, which was always swinging my left hand before the ball touched my right foot.

Beckham made an unpopular decision that was very unfortunate for fans and even soccer observers, namely moving to the L.A. Galaxy. Apart from the fact that MLS is a league whose prestige is very far behind that of the Spanish league, soccer is also not a popular sport in the USA. Beckham was even willing to cut his salary by 70% (from $20 million to $6.5 million) in order to join the team. Crazy, stupid, and ridiculous were the football news headlines about him at the time. But that's the media, they just want to make information that brings in traffic by ignoring the full information.

Blasphemy and criticism continued to be received by Becks because of his decision. Finally, Beck silenced them all. He was willing to lower his salary and join MLS for a reason. There was a clause in his contract that made Becks the richest soccer player. It was a clause regarding the percentage of rights he would get from the club's total revenue, such as merchandise, tickets, sponsorship, and even hot dogs and beer sold at matches. This tremendously increased his income. A smart, careful, and calculated move. In the end, the risks Beckham took by stepping out of his comfort zone allowed him to turn his revenue from $6.5 million to more than $500 million. However, MLS also benefited from it, attendance, TV rights, and ratings all increased. It was a win for Beckham, his club (L.A. Galaxy), and also American soccer (MLS).

Back to the main topic, which is number 23. At L. A Galaxy, Becks used jersey number 23, and that makes me even more convinced that number 23 was a very special number. The number 23 Beckham was strong enough to prove to the world that things they saw were not completely the same as reality. It was also a legacy of Beckham's success in winning his career, even had a positive impact on all those associated with him.

In the year 2023, I wish I could follow what Beckham has done. I don't mean exactly the same because that would be impossible. But at the very least, the decisions I make this year will result in something that makes me win and has a positive impact on many people.

Hi, I am back again

Coretanku

I don't know how long I've been leaving this blog. Don't worry, this blog isn't being hacked, I'm just having trouble managing my time and expressing ideas. So many deadlines for my final examination. Besides, I feel like, I have no passion for writing this blog.

However, I am back again, trying to start my writing habits here.

Actually, I don't know what should I write to start this. But I think I will give some updates about my current life. Ok, let's get it started.

Firstly, I got my article manuscript approved by a journal. I am so happy and a bit relieved although the journal is not my main target. But I think that was the most I could do with this predicament. So, I am just grateful for that.

Currently, I am focused on the preparation of my oral examination. There is some problem, over and over again. I can't explain the detail, but it's drained my energy too much. This phase will be the tough moment this year, yet I am grateful that I finally have a partner who is enough to make me think positively. So I think everything gonna be alright.

That is my recent update, I hope my following writing will be better and more content than this one. But this is my start, and hopefully, I will keep going.

Kopi

coretan

Deadline dan banyak pekerjaan membuat saya kembali kepada kebiasaan lama saya, minum kopi. Nampaknya, belum ada booster yang bisa membuat saya terjaga dan fokus di depan laptop untuk waktu yang cukup lama selain kopi. Bahkan kali ini secara hierarki kebutuhan, kopi sudah bergeser menjadi kebutuhan primer di hidup saya.

Nggak cuma di rumah, saya terkadang membeli kopi di coffee shop agar tidak bosan. Tentu beda rasanya, kopi yang saya buat dengan tangan sendiri dibandingkan kopi yang dibuat oleh barista menggunakan alat. Lebih detail, penyajian kopi di coffee shop juga sangat diperhatikan, mulai dari cangkir/gelas hingga estetika kopi itu sendiri.

Hal tersebut membuat saya ingin memperbaiki cara penyajian kopi di rumah. Mulailah saya membeli cangkir kopi yang lebih estetik. Awal-awal, saya menjadi lebih semangat untuk membuat kopi setiap pagi, entah bagaimana kopi saya menjadi terasa lebih nikmat dari sebelumnya. Padahal cuma ganti wadah.

Waktu terus berjalan bersama dengan kebiasaan ngopi saya setiap hari. Saya kembali menemukan kejenuhan dengan kopi yang saya minum. Apakah harus membeli cangkir yang baru untuk mendapatkan suasana ngopi yang baru lagi?. Beberapa cangkir dengan desain yang modern saya save di aplikasi belanja online. Sudah banyak wishlist yang saya simpan, tapi belum saya check out karena masih melihat-lihat banyaknya desain cangkir yang bagus yang tidak ada habisnya.

Setelah Scroll demi scroll, saya justru semakin bingung mau beli cangkir yang mana lagi. Di tengah kebingungan itu, saya kembali menyeduh kopi. Secangkir kopi panas tanpa gula dengan takaran yang sama seperti yang biasa saya buat setiap hari. Bedanya kali ini saya menggunakan sembarang cangkir (bukan yang biasa saya gunakan). Sungguh kopi dengan rasa yang sama seperti pertamakali saya buat, dan itu membuat saya merenung sejenak.

Saya dihadapkan fakta bahwa, cangkir sama sekali tidak menambah atau mengurangi kualitas kopi. Dalam beberapa kasus memang cangkir bisa membuatnya terlihat mahal, namun dalam kasus lain itu justru bisa menyembunyikan apa yang kita minum.

Ternyata, apa yang benar-benar saya butuhkan adalah kopi, bukan cangkirnya. Tetapi secara sadar di banyak momen saya memilih cangkir terbaik. Dan kemudian membandingkan cangkir-cangkir tersebut.

Mungkin kalau bisa diibaratkan, kurang lebih seperti ini:
Hidup kita adalah kopi.
Pekerjaan, jabatan, uang dan status sosial adalah cangkirnya. Mereka hanya alat untuk menahan dan menampung kehidupan kita. Jenis cangkir yang kita miliki tidak selalu menentukan, atau mengubah kualitas hidup yang kita jalani.

Bahkan, ketika kita hanya berkonsentrasi pada cangkir, kita malah gagal menikmati kopinya. Sama seperti yang sedang saya alami. Saya terlalu fokus mencari cangkir kopi hingga baru menyadari bahwa kopi yang saya seduh dengan cangkir sembarangan ini memiliki rasa yang sama seperti halnya kopi-kopi yang biasa saya buat.

Memandang kopi dan hidup memang tidak sepenuhnya bisa disamakan. Tapi kali ini, sepertinya saya telah diingatkan untuk lebih menikmati kopi, bukan cangkirnya.
