If we were immortals, we should all be miserable; no doubt it is hard to die, but it is sweet to think that we shall not live for ever!
(they say that this is how Bhagat Singh did not feel scared when he thought about death)
If you think about disaster, you will get it. Brood about death and you hasten your demise. Think positively and masterfully, with confidence and faith, and life becomes more secure, more fraught with action, richer in achievement and experience.
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.
