Iron rusts from disuse; water loses its purity from stagnation... even so does inaction sap the vigor of the mind -Leonardo Da Vinci
 

You can tell more about a person by what he says about others than you can by what others say about him -Leo Aikman
 

Do not wait; the time will never be "just right." Start where you stand, and work with whatever tools you may have at your command, and better tools will be found as you go along. -Napoleon Hill
 

We are responsible for what we are, and whatever we wish ourselves to be, we have the power to make ourselves. If what we are now has been the result of our own past actions, it certainly follows that whatever we wish to be in future can be produced by our present actions; so we have to know how to act. -Swami Vivekananda
