To be ambitious for wealth and yet expecting to be poor; to be always doubting your ability to get what you long for, is like trying to reach east by travelling west. there is no philosophy which will help man to succeed when he is always doubting his ability to do so and thus attracting failure. - Charles Bandouin
Say yes to whatever it is. Because if you say yes to it and then you get in the middle of it, and you say, "Uh oh, this isn't really turning out the way I wanted it to," then out of that is born another desire. And as you say yes to that, then it turns out. And you say, "Well, it's still not quite right." So you have another desire... Until eventually you get it exactly right. You cannot get it wrong. No creation is ever complete. Just do it.
