How to Build Confidence Even When You're Feeling Unsure of YourselfEntrepreneurship is a process of taking action despite doubts until, eventually, you quite naturally don't have so many doubts.

We all know someone who oozes confidence wherever they show up. There's no need to be envious. You too can be confident with just a little practice.

Confidence, like many other desirable human qualities, is a skill that takes some patience and time to master. While some people may be born with confidence that knows no boundaries, most of us need a little push here and there to allow our self-assuredness to come to the surface. However, it is an essential skill for any entrepreneur.

So, what can you do to build or boost your confidence?

Gain knowledge through experience.

It may sound obvious, but one key to confidence is knowledge; the more you know, the more confident you'll feel. To be confident, be eager to learn. "The best way to build confidence in a given area is to invest energy in it and work hard at it," said Tony Schwartz, the author ofThe Way We're Working Isn't Working: The Four Forgotten Needs That Energize Great Performance.

In addition, be open to accepting advice or asking for support. Learn to be comfortable using the phrase, "I don't know, but I will find out."

You may not feel very confident about yourself the first time, but you will eventually get there, each time becoming more self-assured.

No one can know everything -- even if they are considered subject experts. Whoever you are, chances are that someone, somewhere knows something you don't.
