As a kid We fell more than thousand times before we start walking on the floor.. What Happened now Why you are thinking too much to try again when you fall... Reason is simple Kid doesn't take failures into head... Now you are taking everything into head..
Thinking too much on whatever we do is a good thing... but not in all the cases.. few cases we have to let it go... and just go for it... just like going in a roller coaster, if you think too much you'll loose the thrill... same way in life, we loose the experiences...
