As you get older, dreams don't have to fade. Actually, the older you get, the more you want to see your dreams become reality. At 49, it's a fair assumption that over half my time on this earth has gone, so I can't afford to waste any time with regrets, sitting on fences, or giving up.
My one big dream is to finish my book. It's been in the making for over a decade now, it's been expanded, revised, gone through several drafts, but is finally in a stage I'm satisfied with. 120+ pages, each page with a full-page illustration, each illustration painstakingly hand-painted. Sure, I could get some hi-tech friends to Paintbox it in, get it done faster, but the results wouldn't be nearly the same. Each brushstroke is mine, and I wouldn't give that up for anything.
I have dreams of seeing the book being a big success, on the shelf of every WalMart, Target, Barnes and Noble, available through Amazon, etc. I expect a Nook and/or Kindle version someday too, but depending on the resolution of the pictures, I might pass on a downloadable version. I'd like you to be able to hold the book in your hands, and actually turn the pages, not just scroll down. If money was no object, I would also love to see it leather-bound, gold leaf letters, so you know you're getting something of real quality.
After a long run on the New York Times bestseller list, will come the inevitable movie, merchandising tie-ins. Lucky my cousin is a copyright lawyer, because I want to retain as much control over my baby as possible, otherwise all bets are off. I'd rather hold on to it than let Disney or some studio who may not really care about the book crank out some substandard piece of crap in the hope of just making a few bucks.
As you get older, you get more possessive of your dreams and seeing them arrive on your terms.
The saddest thing you can do is give up. Quit. Throw in the towel. Sometimes your dreams are all you have, so don't you dare let anyone take them from you.
Some people on here have mentioned dreams of going to New York or Hollywood, trying to break into show-biz. Fair enough. Following your dreams, especially when you're young enough to do so, can light a fire under your butt and drive you to achieve them. But the bigger your dreams are, the more you should be prepared to work for them. And it will be, no lie, a ton of tough, vicious, nauseating work. Rejections, competition, more rejections, every day something may come along to tell you to quit. If your dreams mean enough to you, you won't give them the satisfaction.
Drtooth, if you're still around and willing to give up the pity party for a second, read this. I've seen your stuff on DeviantArt, and it's quite good.
Sometimes quality or artistic integrity doesn't always translate into commercial dividends.
Not everybody gets to be a Muppeteer on Sesame Street. Not everybody ends up a Disney animator. Not everybody lands a lucrative voiceover gig.
When I was younger, playing in bands, each band had a dream of being the next Beatles/Van Halen/Yes/Pink Floyd/Led Zeppelin, etc. Never happened, but still enjoyed trying to get there. Wouldn't trade that for anything.
Don't give up on dreams, folks. Without them, what's the point of getting up every day? That's not living, it's barely existing.
