To know oneself, one should assert oneself.
Only the educated are free.
If you're going through hell, keep going.
Know or listen to those who know.
The secret of getting ahead is getting started.
Problems are not stop signs, they are guidelines.
The wise does at once what the fool does at last.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
That something extra, I believe, is a certain humanity that comes from upbeat and positive human interest letters and success stories. Advertisers like to be associated with those qualities.
