Sometimes I want to be a great man, a historical figure, a dynamo- and I have gone that route, but it has ended in migraines and irascibility. Other times, I simply want to enjoy life, and I know that I am wasting time that a great man could not afford. But I think the desire for fame only comes out of envy for the attention the already famous receive- envy and self-seeking are not good motives. They are evil fuel that poisons the entire machine.
On the other hand, if I am centered on God, and live in his will, then I believe that he will put my talents to good use. There is nothing wasted in God's economy. So again, the central question is do I have the humilty and wisdom to accept that my way leads to suffering, and God's way to glory.
