I think that nothing is impossible when you want to fulfill a dream. A lot of people will tell you that you can't do it, that you don't have what it takes, but if it is in your heart and you feel it, there is nothing that will stop you. It is like the sun - you can't block it: it will shine regardless, if that is what you want.
Did not learned men, too, hold, till within the last twenty-five years, that a flying dragon was an impossible monster? And do we not now know that there are hundreds of them found fossil up and down the world? People call them Pterodactyles: but that is only because they are ashamed to call them flying dragons, after denying so long that flying dragons could exist.
Never say that you can't do something, or that something seems impossible, or that something can't be done, no matter how discouraging or harrowing it may be; human beings are limited only by what we allow ourselves to be limited by: our own minds. We are each the masters of our own reality; when we become self-aware to this: absolutely anything in the world is possible.Master yourself, and become king of the world around you. Let no odds, chastisement, exile, doubt, fear, or ANY mental virii prevent you from accomplishing your dreams. Never be a victim of life; be it's conqueror.
