To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

If you think you can do it, you can.

If you can dream it, you can do it.

It's always too early to quit.

What you do today can improve all your tomorrows.

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

Quality is not an act, it is a habit.

By failing to prepare, you are preparing to fail.
