My question of the month: how can I continually strive for improvement but not drive myself crazy with ever-tougher expectations?
As a corollary, how can I balance constantly recognizing that I’m not perfect with forgiving myself for not being perfect?

Remember – there is no try. Only do, or not do.
Expectations are illusory, as is perfection.
Relish closing the gap between the person you are and the person you want to be.
Nice question. Cheers.
