How destiny is tied to minds

"Be careful of your thoughts, for your thoughts become your words.
Be careful of your words, for your words become your actions.
Be careful of your actions, for your actions become your habits.
Be careful of your habits, for your habits become your character.
Be careful of your character, for your character becomes your destiny"
- Chinese proverb

There are many things you can't control, but you are the one who needs to make choices about how your life will be, forever. A big part of guilts you complain about, belongs to you.
