Quality is not an act, it is a habit.

Never complain and never explain.

Without hard work, nothing grows but weeds.

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

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.
