It's always too early to quit.

You never know what motivates you.

Be gentle to all and stern with yourself.

Quality is not an act, it is a habit.

If you've got a talent, protect it.

The wise does at once what the fool does at last.

The most effective way to do it, is to do it.

By failing to prepare, you are preparing to fail.

Without hard work, nothing grows but weeds.
