The funny thing about failure is how afraid people are of experiencing it. Failure isn't a personal attack on your character or something that defines you. It's a result, or a blueprint showing you exactly where you can improve. Better yet, it's just a measuring stick or a line in the sand showing you where you are at that particular moment. It gives you the gift of opportunity!
There are two types of people in this world; those who are afraid of failure and those who learn and grow from failure. The people afraid of failure will do everything in their power to prevent it or cover it up. They will use every excuse in the book to explain why they failed. This type of performance keeps you on the same level as you were before you began. Nothing is gained but more importantly, nothing lost. You never grow...only remain static.
Those who learn from failure try to push themselves to their absolute limit just to find out how they ran out of gas, when they lost the mental battle, or why their muscles finally gave out on them. Once recovered, these people take honest stock of themselves and their performance so they can learn from it and figure out a way to do their task a little bit more efficiently the next time. Maybe it's something as simple as trying to move at 90% of their max speed in order to maintain an overall faster pace, or doing all movements in round 1 unbroken, or only breaking up movements in two-thirds (for a 15 rep movement, completing 10 reps before breaking and then finishing the remaining 5).
What you should be afraid of is wondering where your next challenge lies. Not being challenged or not failing would be a miserable way to live and a waste of your untapped potential. So when you wake up, look in the mirror. Are you just going through the motions in life hoping not to push yourself too hard or possibly fail? Or are you ready to take on any challenge and put forth your maximum effort regardless of the outcome? Take a risk, learn from your mistakes and understand that you only truly grow when you fail.
