The secret of getting ahead is getting started.
Know or listen to those who know.
To know oneself, one should assert oneself.
If you're going through hell, keep going.
Begin to be now what you will be hereafter.
Either you run the day or the day runs you.
I can, therefore I am.
Expect problems and eat them for breakfast.
Be gentle to all and stern with yourself.
Only the educated are free.
The reason people find it so hard to be happy is that they always see the past better than it was, the present worse than it is, and the future less resolved than it will be.
