Failure is the beginning of success, not the end of the road. I know that it is a blessing, and a situation if you do not go through it, you cannot succeed and discover yourself. When you fail in something, it doesn't mean the end. If you make it a lesson for the beginning, review your current situation and change strategies whenever you feel that they are useless. Human being, but the opposite if there is no failure, we will lose experience and experience in reaching our goal.
“I have not failed. I've just found 10,000 ways that won't work”
Thomas A. Edison
