Do + Not = Don't
Don't compete with anyone. Tend to your own garden and watch your seeds flourish. In other words, mind your own business and watch how much more prosperous you become.
Don't expect anything from anyone. Expectations can lead to disappointments. Don't set yourself up.
Don't blame others for what they can't control. Nobody can control your feelings. If you're unhappy, it's because of something you are dealing with.
Don't be so hasty to argue with a person, even if you know you are right. If you give a person enough time and space, they will reflect on their own actions and realize their faults. It's better that way.
Don't wait for anything to just come to you. Wishes only come true in fairy tails. If you want something, work for it.
