How Do I Increase My Confidence?

I'll keep this simple and straight-forward. =)

1. Interact to as much people as possible since having good companies really make you feel a lot better.
2. Pick up a skill, and be good in it. It can be anything, from playing basketball to football to pool. It can also be something technical like fixing computers or so. Writing poems is a great remedy too. Just make sure you are interested in whatever you wanna do.
3. Write down whatever good deeds you have done for the day in a piece of paper every night and be sure to read it before you hit the bed. You'll be surprised by what you have achieved.
4. Achieving resolutions makes you feel great, too.

Most of the time, people feel depressed and lack confidence because they are unaware of their abilities. Talk to people, ask them about you. Improvise yourself in any way possible. Over time, you'll feel like The King Of The World. Living happily is sometimes A LOT better than earning big bucks. Cheers. Yours truly.
