Self-confidence is having confidence in oneself. This site has published list of 7 tips to immediately increase your confidence. From the article:
Ask yourself, What’s the worst that could happen?. Too often, we place excess importance on potential problems. We all have a certain amount of energy so letâ€™s apply it to creating extraordinary relationships, advancing our careers and meeting our goals INSTEAD of wasting that energy worrying. Take action on what you have control over and minimize risks for what you donâ€™t. Then invest your energy wisely.
Besides all these tips; here is my own tip. Do not fear of anything in life.
In words of Swami Vivekananda – Be a hero. Always say, “I have no fear.” Tell this to everyone — “Have no fear.”. Fear is death, fear is sin, fear is hell, fear is unrighteousness, fear is wrong life. All the negative thoughts and ideas that are in the world have proceeded from this evil spirit of fear.
