Hello Codeforces,

I have an issue when solving problems. If I don't come up with a solution idea within 15 to 30 minutes, I quickly lose interest and don't try to continue or brainstorm at all, and I end up closing the problem. The problem is that my brain is unable to learn new ideas. I mean, even when I try to read the editorial for the solution and find the idea new, I tend to ignore the problem and don't solve it.

This issue started to appear when I began tackling problems with ratings of 1600 and 1500.

Any tips or advice?
