Whenever you are faced with a difficult desicion, you must feel scared of the consequences. Everyone does!
But to give into that fear and not taking the risk may make you regret that decision for your entire lifetime.
Fear of failing is sometimes the only thing that's keeping you from achieving true greatness. If you believe in yourself, you can do it!
Taking certain risks in life gives you immense thrill. Even if it doesn't pan out the way you thought it would, there will be a time when you would be old and rusty and would chuckle about that bold thing you did once. Isn't that worth taking the risk?
Even if you don't succeed, you learn something from the experience which will show you what you did wrong. Using that knowledge, you have a much higher chance of success than you previously had.
And who is to say that you definitely won't succeed? Maybe you will, and that would be because you were bold enough to take that risk.
So you're scared that you might fail and embarrass yourself. But you'll never know unless you go over the edge and take the leap of faith.
Nobody can stop you if you believe in yourself. You are your strongest enemy. If you can win from yourself, you can win the whole world.
If you still fear that you'll fail, remember all the other things that you were scared about 5 years ago. Can't remember it, can you?
All your fears and doubts are temporary but the regret that you didn't even try is permanent.
