Success Is Predictable
The great question of philosophy has always been, “How shall we live to be happy?” The greatest minds of all time have dedicated years, often entire lifetimes, to seeking the answers to this question. Your ability to ask and answer this question correctly for yourself is the key to everything that happens to you and to everything that you accomplish. The worst use of time and life is to work hard to climb the ladder of success only to find that it is leaning against the wrong building.
