“It’s the repetition of affirmations that leads to belief. And once that belief becomes a deep conviction, things begin to happen.” — Muhammad Ali
So even in sleep, train your mind to think of the things you want to become. Thinking is free, so don’t limit yourself.
By planning the night before, the unconscious and subconscious mind will be working to generate ideas and solutions and pull information in the past memory to apply in the situation.
