请问You are what you think you are. 这句话应该怎么翻译,它的出处是什么/

态度决定一切.

We’ve all heard the phrase,“You are what you eat.” The same principle applies to your thoughts.You are what you think you are.I recently came across a cute story that exemplifies this beautifully:
TINY FROGS
There once was a bunch of tiny frogs ...who arranged a running competition.The goal was to reach the top of a very high tower.A big crowd had gathered around the tower to see the race and cheer on the contestants...
The race began...No one in the crowd really believed that the tiny frogs would reach the top of the tower.You heard statements such as:"Oh,WAY too difficult!" "They will NEVER make it to the top." The tiny frogs began collapsing.The crowd continued to yell,"It is too difficult!No one will make it!" More tiny frogs got tired and gave up......But ONE continued higher and higher and higher...This one wouldn't give up!He was the only one who reached the top!All of the other tiny frogs naturally wanted to know how this one frog managed to do it?A contestant asked the tiny frog how he had found the strength to succeed and reach the goal?
It turned out that the winner was DEAF!
The wisdom of this story:
Never listen to other people's tendencies to be negative or pessimistic.They take your most wonderful dreams and wishes away from you -- the ones you have in your heart!
Always think of the power words have.Everything you hear and read will affect your actions!
BE POSITIVE!And above all,be DEAF when people tell you that you cannot fulfill your dreams!Always think:I can do this!
