It is those who concentrates on but one thing at a time who advance in this world. The great man or woman is the one who never steps outside his or her specialty or foolishly dissipates his or her individuality.
Og MandinoThe prizes of life are at the end of each journey, not near the beginning; and it is not given to me to know how many steps are necessary in order to reach my goal. Failure I may still encounter at the thousandth step, yet success hides behind the next bend in the road. Never will I know how close it lies unless I turn the corner.
