Problems are not stop signs, they are guidelines.
Only the educated are free.
The dog that trots about finds a bone.
Without hard work, nothing grows but weeds.
The most effective way to do it, is to do it.
Leap, and the net will appear.
What you do today can improve all your tomorrows.
If you think you can do it, you can.
Go for it now. The future is promised to no one.
Always desire to learn something useful.

Questions have arisen about the policing of science. Who is responsible for the policing? My answer is: all of us.
