In my opinion, mind over matter means that you are what you think. Conscious thoughts drive subconscious thoughts, feelings, and actions. It is a matter of willpower. If a person tells himself he will be happy and successful, he will become happy and successful. if he believes he will be an unhappy, miserable failure, that's what he will become. An example- i had a puzzle made from wooden blocks, which had to be manipulated in a certain way to produce a certain configuration. I thought it was impossible, that there was a trick to it, so i gave up on it. i later found out that there was no trick, it was just very very difficult. Once I knew that it could be done, i committed myself, and did it. simple as that. if you believe you will succeed at something, you will. If you believe you will fail, you will. If you think you suck at bowling, you do, if you believe you can and will get better, you will get better. This applies to a myriad of situations, from things like pain management to career counseling.
