We all gravitate toward what we feel most comfortable doing. We avoid going to certain places or doing certain things, because we're afraid of failing or of looking foolish or any number of other (often unfounded) fears. So instead of taking on a new challenge, we stick with the tried and true. It's called staying in your comfort zone and it is one of the biggest roadblocks to leading a truly fulfilling life.

If you've read this far, you're probably among the majority of people who regret not having taken certain chances in their lives. Maybe it's something from back in High School --like not trying to talk to someone you felt attracted to. Or maybe it was not asking for that promotion at work a few months ago. The point is - each of us likes to hover in our own comfortable little space, often at the cost of missing out on being truly happy. And, let me tell you, there's nothing worse then letting your life slip by because you don't feel comfortable taking chances once in a while.

So what can you do? ---Start with baby steps...

You'll be surprised what a small amount of effort can do for your self confidence. About 6 months past my 40th birthday, I (for the first time in my life) joined a Gym. That was a big step for me, as being a sedate, "computer guy" caused me to really pack on the pounds. I was self-conscious about not only my weight but also my age (I was expecting to see only very thin 20 something's working out). Anyway, as soon as I made the commitment to hit the gym, I started feeling better about myself. It was the simple fact that I had moved past my comfort zone and made a decision to do something different. That small step was the catalyst that got me out of the slump of sitting in front of my computer all day.

Today, I'm at the gym pretty much 6 days a week. I've move past just walking the treadmill, now I do weight training plus I'm taking Yoga and Kickboxing classes. And guess what, those very thin 20 something's aren't really that intimidating after all.

My point is, once you make even a small change it gives your confidence a boost and you start looking for the next challenge. And make no mistake, when you finally break out of your comfort zone, the whole world looks different!
