Competence is the ability to do something successfully or efficiently. One secret is to be able to trust what you are able to do.
Before speaking on a subject become knowledgeable of what you're going to be speaking about so that your confidence won't have a choice but to increase. Try to know everything about the topic before you present your ideas.
Believe in yourself. One of the reasons people are not confident in themselves is that they have already convinced themselves that they will fail before anything has taken place.
Never underestimate the power of the mind. If you believe you will fail, you indeed will!
A better way of thinking is to believe that you will succeed. Set your mind towards succeeding and you will.
Take criticisms, whether it is Good or Bad. Instead of taking the criticisms personally, use every comment and suggestion to make yourself better. This is when you can self-analyze. But also keep a lookout for some criticisms that were never meant to benefit you. Ignore them and move on. And always focus on being a better YOU for YOU.
Remain Focused at All Costs. Keep your composure and stay focused on the PRIZE.
