It is not the possession of truth, but the success which attends the seeking after it, that enriches the seeker and brings happiness to him.

The measure of intelligence is the ability to change.

Glory crowns the deeds of those who expose themselves to toils and dangers.

Plans are nothing; planning is everything

Problems are only opportunities with thorns on them.

The truest wisdom is a resolute determination.

Maybe happiness is this: not feeling like you should be elsewhere.
