Man is not sum of what he has already, but rather the sum of what he does not yet have, of what he could have.

That man has reached immortality who is disturbed by nothing material.

Life is too short to hold grudges or dwell on the past.

Success is not about seeking external fame; it's about making a positive impact in the lives of those around you.

Without some goals and some efforts to reach it, no man can live.

Do not wait for anybody or anything. Do whatever you can. Build your hope on none.

External nature is only internal nature writ large.
