Idealists get hurt. Plain and simple.

If you are going to be an idealist, you must be prepared to get a big-ass slap in the face every once in a while when one of your ideas falls through. However, the pain from this slap in the face will hopefully make it all the more satisfying when one of your dreams comes true, allowing you to laugh in the face of those who doubted you. As my mother likes to say (among many, many other things) "What doesn't kill you can only make you stronger." I guess I must be a very strong person indeed.
