It's always too early to quit.
Only the educated are free.
If you think you can do it, you can.

To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
The most effective way to do it, is to do it.
Local innovation and initiative can help us better understand how to protect our environment.
Why has it seemed that the only way to protect the environment is with heavy-handed government regulation?
