There are only a few times in life when you really truly receive a fresh start. When you're born, when you first move out of your parents' home, and when you hit that stage in adulthood where you've run out of f*cks to give.
Life has a way of antagonizing you and testing your patience. Sometimes it will seem like you're only preparing for the next worst thing instead of enjoying the many great things that life has to offer. You will feel stuck and frustrated. Maybe even resentful.
But eventually you'll hit a wall and realize that you've ran out of cares for things that are not your own concern. Don't waste your time charging that wall or trying to bring it down. Climb it and leave all the shit behind you.
