If you think you can do it, you can.

I can, therefore I am.

Quality is not an act, it is a habit.

Without hard work, nothing grows but weeds.

What you do today can improve all your tomorrows.

Know or listen to those who know.

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

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

Problems are not stop signs, they are guidelines.
