good.bad.normal.

Appreciation.

bad days,
everyone has it. when we are going through it, we complain, we blame, we are not happy.

good days,
we enjoy them. but most of the time, we take them for granted. and sometimes we even complain that it passed to fast.

normal days,
we call them monotonous, boring.

Gratitude.
Be thankful for what you have, instead of complaining of what you don't have.
