What you do today can improve all your tomorrows.
It's always too early to quit.
The wise does at once what the fool does at last.
The most effective way to do it, is to do it.
Go for it now. The future is promised to no one.
Without hard work, nothing grows but weeds.
By failing to prepare, you are preparing to fail.
Well done is better than well said.
The secret of getting ahead is getting started.
The dog that trots about finds a bone.
Success breeds success, and failure leads to a sort of fallow period.
