There is no reward in life without risk.
You just have to know what it is that you're risking.
If you're risking something like embarrassment, well, I think you just to get over that.
I embarrass myself at least once a day.
I'm prone to it.
Therefore, I'm used to it.
Once you can get over yourself, you find that life is a jewel. Life is beautiful. Life is worth living. You can sit there, on your couch, for as long as you like, but life will pass you by. As a matter of fact, I'm of the strong belief that the longer you sit, the harder it is to get up. So GET UP! Start living. Start risking. You never know, you might just have a whole lot of fun.
