The secret of life is not enjoyment, but education through experience.
All the powers in the universe are already ours. It is we who have put our hands before our eyes and cry that it is dark.
Doing is very good, but that comes from thinking… fill the brain, therefore, with high thoughts, highest ideals; place them day and night before you; and out of that will come great work.
We are responsible for what we are, and whatever we wish ourselves to be, we have the power to make ourselves. If what we are now has been the result of our own past actions, it certainly follows that whatever we wish to be in future can be produced by our present actions; so we have to know how to act.
