I hear a lot that doing competitive programming is important to land jobs and that it would improve your ability to solve problems, however; I hate it and I suck at it so much. I don't see improvement except for knowing how to solve a certain problem and I forget about it after some time.

I can't stand doing any kind of abstract, unrealistic problem solving for whatever reason. I love solving real-world problems that actually matter and provide an actual value on the other hand.
