If you think you can do it, you can.
The secret of getting ahead is getting started.
Problems are not stop signs, they are guidelines.
Things do not happen. Things are made to happen.
Go for it now. The future is promised to no one.
If you're going through hell, keep going.
To know oneself, one should assert oneself.
Know or listen to those who know.
Be gentle to all and stern with yourself.
It's always too early to quit.
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.
