Be positive. Look on the “can do” side of things rather than the “can’t do”. You’ve accomplished lots in your life and you will accomplish lots more in the future.
Be in charge of your thoughts at all times.
What is a thought? It’s just a question that you’ve asked yourself and the thought is you’re answer. If you’re thinking negative thoughts, you’re probably asking a negative question. Change the questions to be more positive.
Whenever you feel a negative thought coming, STOP, THINK, and say is this really important in the grand scheme of things?
Do you let the words of others affect you? Do you mind what they think of you? Remember that no one can make you feel inferior without your consent. It’s not what they say to you that’s the problem it’s what you say to yourself after they have stopped talking that’s the problem.
Change the way you think.
