You can never predict when inspiration strikes

A person told me that i was wasting away my talents, that i was wasting away my opportunities.  Even though i rebelled against it and stated that it wasn't right, i was completely wrong.  Its not about doing everything perfectly, its about grabbing the opportunity that is right in front of you. I know what  I am good at and if  I don't give input to it, I am doing a great deal less to what I know I'm good at. If you are not taking that opportunity, how on Earth can you give anything to anyone?
