Problems are not stop signs, they are guidelines.
Without hard work, nothing grows but weeds.
Leap, and the net will appear.
I can, therefore I am.
If you think you can do it, you can.
Do not weep do not wax indignant. Understand.
Know or listen to those who know.
Things do not happen. Things are made to happen.
The dog that trots about finds a bone.
Well done is better than well said.
If we would have new knowledge, we must get a whole world of new questions.
