You must condition yourself positively. Being positive is an attitude you can develop. Your attitude and your mood must always be under your control, so control them. You can do this by learning to block the negativities which surround you. Negativity will drain your spirit and your desire to be successful.
Surround yourself with positive people and their attitudes will push you ahead. Strive to live in the present and do not allow your limitation to weigh you down. The more difficult your situation is, the more positive you must be. Forget your past failures and anxieties of the future. In the middle of any difficult lies your opportunity, but all this depends on how you look at things. You have the chance to be a king, if your have the heart to stay positive under all circumstances. Believe in yourself! Be strong, and you will surely get to the top.
