Go for it now. The future is promised to no one.
After a storm comes a calm.
Without hard work, nothing grows but weeds.
Problems are not stop signs, they are guidelines.
The wise does at once what the fool does at last.
To be a good loser is to learn how to win.
Leap, and the net will appear.
If you think you can do it, you can.
Know or listen to those who know.
To know oneself, one should assert oneself.
The human imagination has already come to conceive the possibility of recreating human society.
The product of the scientific imagination is a new vision of relations - like that of artistic imagination.
