After a storm comes a calm.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
Problems are not stop signs, they are guidelines.
You never know what motivates you.
The most effective way to do it, is to do it.
Without hard work, nothing grows but weeds.
It's always too early to quit.
The dog that trots about finds a bone.
If you think you can do it, you can.
The research rat of the future allows experimentation without manipulation of the real world. This is the cutting edge of modeling technology.
