It's always too early to quit.
Go for it now. The future is promised to no one.
Things do not happen. Things are made to happen.
The wise does at once what the fool does at last.
Never complain and never explain.
The dog that trots about finds a bone.
Problems are not stop signs, they are guidelines.
The secret of getting ahead is getting started.
Be gentle to all and stern with yourself.
Without hard work, nothing grows but weeds.
Aging seems to be the only available way to live a long life.
