Mistakes are part of the learning process. One cannot deny that mistakes play an integral part of ones growth. Success is sometimes defined as how much you strive hard from the mistakes you made. 

Never be afraid of committing mistakes. Sometimes it is a ticket for one's success. Just be reminded that before you do things, you must carefully act and think of the consequences of your actions.

Mistakes may sometimes drag you down. So think twice before doing anything. Think twice before executing it.
