You determine your own line of future action.

You determine your own line of future action, inasmuch, as you decide what condition of life you will exist in by the direction of your aspirations. 

If you are one who is always aspiring to be better than you are, you will inevitably become so on the principle that prayer or willpower is the operative influence, which shapes your future career. 

So; on the other hand, if you are one who is content through life to remain what you are, you will never rise into any other position until new thoughts and aspirations are quickened into being by contact with life in the next world.
