He who would reach the desired goal must, while a boy, suffer and labor much and bear both heat and cold.
[Lat., Qui studet optatam cursu coningere metam
Multa tulit fecitque puer, sudavit et alsit.]
If you are pleased with what you are, you have stopped already. If you say, "It is enough," you are lost. Keep on walking, moving forward, trying for the goal.
For what purpose humanity is there should not even concern us: why you are here, that you should ask yourself: and if you have no ready answer, then set for yourself goals, high and noble goals, and perish in pursuit of them!
I was originally supposed to become an engineer but the thought of having to expend my creative energy on things that make practical everyday life even more refined, with a loathsome capital gain as the goal, was unbearable to me.
I demand pretty aggressive goal setting and a commitment to measured progress towards those goals because I don't like surprises. I don't even like good surprises.
