Giftedness easily becomes a social disability if your environment isn't good for it. The education system isn't ready to handle you constantly being ahead of the class? Get ready to sleep in school as the best years to take advantage of it pass by. Your topics of interest are too complex for everyone else around? Have fun enjoying your friendships less than everyone else. You don't mask your intelligence? Here, have 10 lottery tickets to get bullied, no, you can't return them. Congratulations, you graduated from college. Do you have the money for a masters degree? Oops, guess you studied for nothing. Got into debt and got a masters, but the job market isn't booming? Do you have rich parents, or rich friends? Aw shucks, guess you couldn't network your way into the type of job you would have liked.
Being intelligent helps, if you're patient, hard-working, and have the means to look out for the less conventional options, but not so much as one would instinctively think.
