Lost my passion and interest in what I used to love Story: Great MSc Computer Science student lost interest in what he used to love

------ PAST ------

Since I was a kid, I was really passionate about the things I love. I was always ahead of my schoolmates and always prepared in advance for the material. Simply to say, I loved learning new things.

When I got into high school puberty hit me and I kind of get out of track in the first two years, but I hit hard in next two years excelling with GPA 5/5 (I was put in class of highly competitive students). Last year of high school, I did find something that gave me hard dopamine spikes, and that was programming. Just in 1 year, I earned 3rd place on State Competition and manage to get to National Olympiad. I also attended competitions of physics and mathematics. I loved the thrill of the challenge.

Took Bachelor of Computer Science, though I learned hard only the subjects that I love. I was great student (top 10 in my area) and I successfully finished it with a GPA of 4.5/5. Meanwhile, I found high interest in Artificial Intelligence and subfield of Machine Learning. I did AI courses online from Stanford, Coursera etc., since I started my bachelor studies (4 years ago) and I really liked that area. I finished my diploma thesis related to pattern recognition and my bachelors in record time.

----- RECENT ----

But after finishing bachelors everything changed. Seems like I was worn out, burned and unmotivated. I got programming job that was paid good but I hated. I completely lost my interest in programming. My driving force just dissipated in air.

Now, I got really good scholarship that got me in one of the top research universities in Europe. Still, my interests in AI dropped to 0. Seems like nothing is challenge now and I don't feel the dopamine spikes that I felt when I was discovering the field (which was novelty for me). Obviously my GPA is not good because of this (even though there are easy subjects that I've already have lot of pre-knowledge but still no motivation to learn them). I am now in my second semester of my studies. I took job as research assistant still don't feel motivated at all.

----MY OWN OPINION ----

From knowing myself I would say that I only thing that makes me motivated is learning new stuff from new fields. Whenever I learn something from one field I easily get bored and switch to something new. I put my whole effort and strength to learn it (when I am motivated). I could not specialize in one thing because of this and I am angry on myself.

I never suffered from depression, I always sleep 7-8h, eat regularly, love to go to the gym, love reading books. I was taking some supplements on my own thinking that I'm suffering from depression but without any help.

Please write here your opinion and advice, I would really appreciate hearing it. 

Thanks a lot in advance.
A senior professor I am acquainted with once uttered, "In choosing one's career, the point is not to find what you like most; the point is to find what you dislike least." I find it wise and would like to share it with you.

I would say you may first study a field you dislike least at the present stage and at the same time try to search what truly interests you.
