Human potential is the same for all. Your feeling, 'I am of no value', is wrong. Absolutely wrong. You are deceiving yourself. We all have the power of thought — so what are you lacking? If you have will-power , then you can do anything. It is usually said that you are your own master.
How lovely to think that no one need wait a moment, we can start now, start slowly changing the world! How lovely that everyone, great and small, can make their contribution toward introducing justice straightaway... And you can always, always give something, even if it is only kindness!
