Without hard work, nothing grows but weeds.
Quality is not an act, it is a habit.
After a storm comes a calm.
To know oneself, one should assert oneself.
It's always too early to quit.
By failing to prepare, you are preparing to fail.
What you do today can improve all your tomorrows.
The wise does at once what the fool does at last.
Begin to be now what you will be hereafter.
Go for it now. The future is promised to no one.
Triumphant science and technology are only at the threshold of man's command over sources of energy so stupendous that, if used for military purposes, they can wipe out our entire civilization.
