Always desire to learn something useful.
Without hard work, nothing grows but weeds.
Expect problems and eat them for breakfast.
The secret of getting ahead is getting started.
The dog that trots about finds a bone.
Go for it now. The future is promised to no one.
Things do not happen. Things are made to happen.
You never know what motivates you.
Do not weep do not wax indignant. Understand.
Leap, and the net will appear.
Science fiction is no more written for scientists that ghost stories are written for ghosts.
