Sometimes you win,
Sometimes you learn
Every difficulty is an opportunity in disguise.
The things that annoy you are saving your brain.
The sense of confusion you feel as you workout a problem like the chaotic brain just before you reach the answer of a riddle much like the annoyance of that pet peeves or the person you disagree with that slight push out of your comfort zone is your brain creating neurons and developing new wiring.
Your body rebuilds itself from a blueprint based on a program.
That program is created from your beliefs and emotions so make sure you're feeling good and your intentions are positive.
