Only the educated are free.
Be kind whenever possible. It is always possible.
Without hard work, nothing grows but weeds.
Do not weep do not wax indignant. Understand.
Leap, and the net will appear.
Things do not happen. Things are made to happen.
It's always too early to quit.
Begin to be now what you will be hereafter.
The wise does at once what the fool does at last.
You never know what motivates you.
All science is either physics or stamp collecting.
