Problems are to the mind what exercise is to the muscles, they toughen and make strong

Don't duck the most difficult problems. That just insures that the hardest part will be left when you're most tired. Get the big one done - it's downhill from then on.

Anybody can do just about anything with himself that he really wants to and makes up his mind to do. We are capable of greater things than we realize.

Always remember that problems contain values that have improvement potential.

Formulate and stamp indelibly on your mind a mental picture of yourself succeeding. Hold this picture tenaciously. Never permit it to fade. Your mind will seek to develop the picture...Do not build up obstacles in your imagination.

The mind, ever the willing servant, will respond to boldness, for boldness, in effect, is a command to deliver mental resources
