I am writing from a fake account, on my original account I started doing CP about 7 years ago, reached the GrandMaster level, and participated in ICPC WF.
However, In 2020 I stopped doing CP, recently I wanted to solve problems again but I feel like I don't like it anymore, also I am struggling with medium 2000 problems, these problems I could solve in no time at my prime days :(
I was wondering, did anyone face the same issue before? And how did you overcome it?
What did you do during that time period, I'm curious.
You are a Chinese right ??
and also from Shanghai right I know you personally
but I didn't know you started smashing CP again : )
good luck : )
Well you can start with reading adamant(maths) blogs, getting into discussion on cp servers like AC. reading is more lazy and easy to do , so it will boost motivation.
Then, when you have some alternate solution for some discussion , you can try to implement it.
do it for sometime. maybe it will help. good luck !!
