And we aspire for greatness

Many a times I find this question bothering me. We all aspire to do great things to achieve big in life, but how can that be accomplished if we get stuck in the routine of life ? Time and again I have felt that a great deal of passion and determination is required to accomplish something. Where do we find the passion ? How do we renew our inspiration each and every day ? Maybe we should derive it from the small things that give us pleasure, things that give us strength.
First we must know our goal in life. Then we must keep renewing our strenght by reading , by doing things that take us closer to the goal in small steps.
