Always desire to learn something useful.
Only the educated are free.
Do not weep do not wax indignant. Understand.
Know or listen to those who know.
Be thine own palace, or the world's thy jail.
After a storm comes a calm.
Go for it now. The future is promised to no one.
If you think you can do it, you can.
It's always too early to quit.
What you do today can improve all your tomorrows.
The object of pure physics is the unfolding of the laws of the intelligible world the object of pure mathematics that of unfolding the laws of human intelligence.
