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 willpower, then you can change anything. It is usually said that you are your own master.
His Holiness the Dalai Lama
Mind, which is like lightning, a breeze, or passing clouds,
Is coloured by its various thoughts of everything under the sun,
But when examined thoroughly is found to lack a basis or origin.
Just like a mirage on the horizon, it is devoid of essential nature.
While being empty, it appears; and while appearing, it is empty.
