“If they can make penicillin out of moldy bread, they can sure make something out of you.” Muhammad Ali
What this quote means is that within each and everyone one of us, there is something valuable. Moldy bread, which most people would think worthless and toss away, in the right hands can be made into one of the greatest medicines we have. The same thing applies to you. Within you is a gem, and even if most people cannot see it, it is there. Find a way to expose that gem, or find the right person to help you get to that gem.
