It's always too early to quit.

To know oneself, one should assert oneself.

If you think you can do it, you can.

Only the educated are free.

Problems are not stop signs, they are guidelines.

Begin to be now what you will be hereafter.

Things do not happen. Things are made to happen.

What you do today can improve all your tomorrows.

The dog that trots about finds a bone.
