as long as you don't have too many of them in mind. life isn't long enough to do all of them. but sure, if you're willing to trade everything else for any one thing. by my measure though, it is better to avoid messing up the world you still have to live in. then whatever gives you gratification that you can do without doing that. i mean, why waste trying to impress anyone else, what you might otherwise have enjoyed?
Put ten dollars away every month and don't touch it. Even if you have another savings account and you add to it already.
