Try and Try Again
Always be prepared to make mistakes. Mistakes are not only part of life, they are part of learning. The only people not making mistakes are dead people. If you are alive: you will make mistakes. Make the most of them, just try and try again. So you don’t know everything? Join the crowd.
Take your time watching others do a combination, but then make sure you try it yourself. Even if it is wrong, slow, you only remember the second half, whatever, it is important to try. You can only ride a bicycle by riding it. Debating the issue endlessly will not help you.
NO BODY IS PERFECT! To progress you need to leave the internal critic outside the door.
