You will never reach your destination if you stop and throw stones at every dog that barks.

Don't deliver an essay with so many points. No one can absorb it. Just say one thing... Of course, you can say the point in many different ways over and over again with different illustrations.

An optimist sees the oportunity in every difficulty.

To try to be safe everywhere is to be strong nowhere.

Decided only to be undecided, resolved to be irresolute, adamant for drift, solid for fluidity, all-powerful to be impotent.

It is one thing to see the forward path and another to be able to take it. But it is better to have an ambitious plan than none at all.

Don't argue about the difficulties. The difficulties will argue for themselves.
