The Power of Wish

I separate my wishes from what I can do and I wish always more than I can. This philosophy I adopted from Vedic lectures I got from a friend. They say our wishes have the great power because they come true. And if you don't wish more than you can, you'll never get further than you can. When we are born we can just scream, eat, sleep and shit. Our wishes are guiding us. Through them we can learn to do more. The moon was always unreachable. And even birds could not fly so high. So what?
