You never know what motivates you.

Things do not happen. Things are made to happen.

By failing to prepare, you are preparing to fail.

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

If you think you can do it, you can.

Well done is better than well said.

To know oneself, one should assert oneself.

Know or listen to those who know.

Quality is not an act, it is a habit.
