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 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.
Courage is required to make an initial thrust toward one's coveted goal, but even greater courage is called for when one stumbles and must make a second effort to achieve. Have the determination to make the effort, the single-mindedne ss to work toward a worthy goal, and the courage not only to face the challenges that inevitably come but also to make a second effort, should such be required.
