It can take more heroic effort for a homeless "bum" on the street to clean himself up and get a steady job in a department store than for a man who had a good childhood with positive role models, health, and a good education to become a millionaire.
We are all dealt a hand in life, and each hand is incredibly unequal. It's what you do with what you've been dealt that counts.
That's why even though I've become very successful according to the world, I don't consider myself any better than the bum on the street. I don't know his story. I don't know what kind of ghastly circumstances made him give up for the time being. I used to look down on people who didn't live up to my own potential, but I found out that everyone's potential is different.
There are some true heroes out there who have pulled themselves out of emotional illness and off the streets and into a cafeteria job, for example. Not many, perhaps, but a few. The luck of the draw can somewhat determine a man's potential, and it is up to each man to improve his station in life the best he can.
The bird born with a broken wing is no less a bird than his peers who soar in the sky, for it may be much more difficult for that bird to attain his worms than for his soaring companions.
