Most Men Are Essentially Dead By Thirty.

Each Man Must Learn His Own Ideal And Try To Accomplish It: That Is A Surer Way Of Progress Than To Take The Ideas Of Another.

One Makes Mistakes; That Is Life. But It Is Never A Mistake To Have Loved.

Skepticism, Riddling The Faith Of Yesterday, Prepared The Way For The Faith Of Tomorrow.

Be Reverent Before The Dawning Day. Do Not Think Of What Will Be In A Year, Or In Ten Years. Think Of To-day.

Take Possession Of The Air, Submit The Elements, Penetrate The Last Redoubts Of Nature, Make Space Retreat, Make Death Retreat.
