"Ars longa, vita brevis, occasio praeceps, experimentum periculosum, iudicium difficile."

I'm going to adopt this as my motto. 

Translation: 

Life is short,

the art long,

opportunity fleeting, 

experiment treacherous, 

judgment difficult. 

Because really, Carpe Diem and Cogito Ergo Sum have been done to death.
