Be gentle to all and stern with yourself.
You never know what motivates you.
Know or listen to those who know.
Go for it now. The future is promised to no one.
The secret of getting ahead is getting started.
Be thine own palace, or the world's thy jail.
Never complain and never explain.
The wise does at once what the fool does at last.
If you think you can do it, you can.
Who seeks shall find.
We have found that where science has progressed the farthest, the mind has but regained from nature that which the mind put into nature.
