The dog that trots about finds a bone.
You never know what motivates you.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
After a storm comes a calm.
Do not weep do not wax indignant. Understand.
What you do today can improve all your tomorrows.
If you can dream it, you can do it.
Either you run the day or the day runs you.
Begin to be now what you will be hereafter.
As for everything else, so for a mathematical theory: beauty can be perceived but not explained.
