A man proves himself fit to go higher who shows that he is faithful where he is.

A man that will not do well in his present place, because he longs to be higher, is fit neither to be where he is nor yet above it; he is already too high and should be put lower." Do that which is assigned thee and thou canst not hope too much, or dare too much.

What a man does, that he has.

In himself is his might.

Don't waste life on doubts and fears.
