Yes yes yes - Minnie is right on!
Very good to see you here Jess!

Not sure how good groups like Mensa are for helping with problems like the one you present: wanting to move towards reaching your real potential, but feeling like you've missed the *usual* boat, but it might be a place to look.

There are colleges in the u.s. which might be a great fit for you, the internet is a great resource for finding exactly what you are looking for smile
Heck, perhaps one of these new-fangled online universities. I am entirely unsure of the process you'd need to take to apply.

You should also consider that moving towards *your* full potential might not require formal education, degrees, etc. There are still a few fields in the world where you can just grab some books and get the ball rolling on your own: Computer programming, a good way to make money to pursue more formal education down the road, if you do want that.
If you find your interests lie more in the language arts realm: Writing. Yes, you do have to educate yourself for this, read the classics, read good criticism, read read read, but there are of course many examples of great writers who don't have phds...

Anyway, hope I am not speaking out of turn, but there are lots of ways to skin this cat!
