I began to learn about CP during the last quarter of my first year at college through the CP community at our university. I created an account on Codeforces and attempted to solve random problems, often aiming for higher rating problems to prove to myself that I was skilled.
I wasn't following any strategy, and there was no one to guide me. I simply pick random problems with ratings higher than my actual skill level and try to solve them even if it takes me days to do it.

I managed to reach a Specialist with no knowledge. and after gaining some random knowledge in various topics, I stopped training and CP for almost a year, barely solving problems when I was bored. Now, I realized all my mistakes and understand that I wasn't actually training; I was simply wasting my time.

The issue I'm facing now is that I'm in my third year at college, and in my country "Egypt", passing a job interview requires more than just problem solving you also need to know about the technology stack relevant to the position. Additionally, I have to complete my graduation project, which involves studying some AI. While I know that FAANG and similar companies do PS only interview, I know that it's very difficult to land a job there, even with qualifications. The possibility of reaching the interview stage is around 1%, so I have ~1 year to make all of this.
(getting better at CP to reach ICPC learn some technology stack like backend development and study AI for graduation project)

So, let me ask you
have you regretted quitting CP?
Is it worth staying another year in college to reach ICPC?
Would I miss a lot if I quit now?
Since I've already walked on this path, it's hard to leave because I haven't achieved anything.

I'm 20 years old am I too old to achieve success in CP?
I have been diagnosed with ADHD would that affect the process?
