To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
It's always too early to quit.
Never complain and never explain.
Go for it now. The future is promised to no one.
Problems are not stop signs, they are guidelines.
By failing to prepare, you are preparing to fail.
The secret of getting ahead is getting started.
The most effective way to do it, is to do it.
The dog that trots about finds a bone.
It's weird, I never wish anything bad upon anybody, except two or three old girlfriends.
It's our nature: Human beings like success but they hate successful people.
