Fear is the devil's handiwork. If you never try, you'll never know. If you never venture outside of your comfort zone, you could be passing up the opportunity of your lifetime. Courage is not the absense of fear, but acting despite it.
If you are not falling you are not making mistakes and if you are not making mistakes you're just doing the same old things you already know how to do .... boring. ... failing is the first step in learning. .. Don't be scared of it. .. embrace it and learn and grow and thrive. ... that'll be $10.35 please :)
You will be successful, maybe not the first, second or even the fifth time. .. Read the early life of Abe Lincoln. .. He tried to become a lawyet a few times and failed. . He tried to get elected a few times and failed ... the common thread in success is perseverance. .. And I'll waiver the advice fee this time :)
You grow thicker skin after a while... watch a lot of ba<x>seball where a guy can become a millionaire by failing to hit the ball successfully seven out of ten times at bat.
Don't look down, then again you've probably heard that one plenty of times
I think whatever happens, it won't be worse than death, and death doesn't sound too bad itself
If you want something that bad then you will never be happy. Just chill and do your best. If you fail try again or find a new ob<x>jective
