This is an off topic.

I heard a story of a Romanian student. He was board to do coding and watch Netflix all day and always demotivated. So he had an idea. He coded a program that will force him to code for 5 hours and the program won't let him surf internet, social media or watch netflix. This really helped him. Is there any software that will do so to help me?? I'm looking for one.

How do I proof the existence of a solution of Greedy, Number theory and mathematical problems???

How to self learn and solve problems?

If you visit my profile you will see that I'm not that good at problem solving. I solve only A type problems I have 1 year left to complete my college. I didn't do well in ICPC regional contest. I want a good CodeForce profile within this one year and a good problem solver as well. Is it even possible to do so??!!!
