Listen to winning stuff. The more you hear sounds of winning, the easier it is to understand winning ways. Permission is easier when you repeat the message. Hang around winners. The best place to learn winning ways is from a winner.
Permission comes from winning thoughts and ideas.
Take winning actions. There's no such thing as a passive winner. Permission is a winning action. Act like a winner. As it evolves in your psyche, your thinking will begin to automatically adjust to disappointments and set-backs, and find a way to get around them or overcome them.
