Problems are not stop signs, they are guidelines.
The dog that trots about finds a bone.
To know oneself, one should assert oneself.
Know or listen to those who know.
Begin to be now what you will be hereafter.
What you do today can improve all your tomorrows.
By failing to prepare, you are preparing to fail.
If you can dream it, you can do it.
Leap, and the net will appear.
If you think you can do it, you can.
The whole business of marshaling one's energies becomes more and more important as one grows older.
