It's always too early to quit.

Things do not happen. Things are made to happen.

Without hard work, nothing grows but weeds.

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

Quality is not an act, it is a habit.

The dog that trots about finds a bone.

Do not weep do not wax indignant. Understand.

If you think you can do it, you can.

Well done is better than well said.
