The part of life which we really live is short.
No one's so old that he mayn't with decency hope for one more day.
You should keep on learning as long as there is something you do not know.
Refrain from following the example of those whose craving is for attention, not their own improvement.
Lay hold of today's task, and you will not depend so much upon tomorrow's.
It's all in your headJ you have the power to make things seem hard or easy or even amusing. The choice is yours.
