Grinding mentality becoming obsessional

Does grinding mentality, the fact that we always want to evolve, become a better person becomes obsessional?

I mean, we are not happy with ourselves, we always want to become better at everything.
Our enemy is ourselves. Every day is a day to learn, to become a better version than the day before.

I guess people can feel that we are not happy with ourselves.
Maybe it can affect our confidence for some things?

What is the solution? How to react?

I guess daily meditation, introspection and some rests are good to take some distance
