"Strive not to be a success, but rather to be of value.” —Albert Einstein. Do you agree?

Absolutely agree! Success often follows when you focus on providing value.

both are directly proportional to each other tho :)

Yes, that's true

I don't think it's necessarily successful to be valuable, but success is definitely valuable

I definitely agree. Even if adding value to the world doesn't lead to success, you've sent ripples of change out into the world.
