Self-realization is the key to success. I was complaining to God that I didn't have a better pair of shoes until I met a person who did not have feet. Being oblivious to blessings showered upon us, we incessantly crib about so many things in life. We fail to realize our importance and the value of our body. Swami Vivekananda once said "Leave aside your thought of poverty. In what respect are you poor? Instead of brooding and pondering on our petty desires, we should rather see what we have". This is the first step towards success.
