In all human affairs there are efforts, and there are results, and the strength of the effort is the measure of the result. Chance is not. Gifts, powers, material, intellectual, and spiritual possessions are the fruits of effort; they are thoughts completed, objects accomplished, visions realized.
The Vision that you glorify in your mind, the Ideal that you enthrone in your heart — this you will build your life by, this you will become.

As A Man Thinketh (1902)
