1: Pump Up Your Self Esteem: Be honest and brave enough to take a look at yourself; find out who you are and where you presently are in life. Learn to have self discipline and silence your inner critic. Stop listening to that little voice of doubt that says you're not good enough or that other people are better than you. Use this opportunity to figure out how you can improve - and trust me, you can do better. An important step is for you to take stock of your achievements.
2: Overcome Shyness: Shyness prevents you from letting people see the real you, because you're afraid to say or do the wrong thing or to appear awkward. The problem is, by being shy and hanging back from the rest of the crowd, you're already projecting yourself as awkward. You have to show respect, empathy, and recognition to others. All you need to do is emerge from your shell and be alert; always open yourself to interact with people. Always show your enthusiasm and radiate optimism, and you will naturally attract people's attention.
3: Get Out There and Just Do It: Many of us don't think we are capable of doing the things we want because we're not sure about ourselves. Again, there's the dreaded voice of doubt. What you want is to be fearless enough so you'll be able to tackle all the things you've ever dreamed of doing. Fear of failure is a big factor in the crumbling of our self-confidence.
4: Dress for Success: Instead of putting on clothes that only make you feel drab and dull, choose the very things that make you stand out and feel special. It all starts in how you feel; and if you feel good about yourself, you will really act more confidently (and intelligently) throughout the day.
