I think you need psychologist not codeforces (:

I recommend you to search for self-improvement videos or books. You can feel like yourself being motivated even without any serious efforts.

Find a person who you respect, who you can rely, or who you can learn.

I asked myself this kind of questions before, just don't push too hard on yourself, take a break and eventually everything will get better, believe my I was in this situation before.

You can watch screencasts of Petr Mitrichev ! I used to do so , whenever i feel bored ! u can try too .

Just remember that if you're not willing to sacrifice to reach your goals, you actually do sacrifice ... your goals.

Here is one nice tip

Saitama-sensei teaches me how to not give up and live my enjoyable life. You know what he does every single day, don't you?

On more serious note: Don't forget to reward yourself. Have a treat after you accomplished something!

Check out The Myth of Sisyphus essay by Albert Camus. "...Sisyphus, a figure of Greek mythology who was condemned to repeat forever the same meaningless task of pushing a boulder up a mountain, only to see it roll down again. The essay concludes, 'The struggle itself ... is enough to fill a man's heart. One must imagine Sisyphus happy'." https://en.wikipedia.org/wiki/The_Myth_of_Sisyphus

Actually after spending > 10 years doing competitive programming I think that CP taught me most of these things.

In my first ~ 7 years I failed in many important competitions and had miserable life. After I accepted that it was ok to fail, and just try to improve myself instead of worrying about results, I did much better.

How to be more confident?

You need to have real skills to become more confident. Just focus on improve different skills. For me I just code more and taught others. Confidence follows naturally.

How to fight fear?

I was usually frightened in important competitions. At my last ICPC WF I finally accepted that it was ok if I do badly. I prepared for that contest for so many years, and I could not prepare any better — so I just accept whatever happen.

How to never give up?

How to keep the fire inside burning?

I think you should instead try to figure out what you want to do. For me I've tried several other things — and I realized everything else sucks. So I just stick to programming.

Just be a REPEATER!!!
