I too was in gifted studies in school, bored most of the time, I've sort of fallen into places where I worked, could tackle ANY problem given to me IF it fit my desire, never needed to study, tests were easy, etc... But I'm not afraid to talk to people, give speeches, or whatever is required of me on a day to day basis. This is where we may diverge.
I'm 32. I procrastinate because it's rewarded me, unjustly at times. I've fallen into the mindset that if you wait long enough, something will happen and you can ignore it or deal with it when it becomes an issue. I just filed my last two years of taxes... they owed me money, so no fines. Most people don't know that and the knowledge of that only encouraged me to wait longer. I didn't "need" the money, so I didn't file. Like I said before, I kind of fell into jobs. Right place, right time. I'm a full time senior developer for a fortune 100 company. Pay isn't "awesome" but it's enough for me to enjoy my life. I get to drive my sports cars (and, erm, sporty cars... '93 Z24 Cavalier -> '02 Pontiac GP GTP -> '04 RX8 -> '08 MX5.)
The only "problem" (not for me, for others looking at my life) is that I've been single for the past 12(?) years. It's been so long I don't remember what month it ended. No, not single and dating either. I just haven't ever asked anyone out. Go back to the "things always worked out" mentality, and maybe put in a nudge of dislike for the societal normal process of "Guy asks Girl." My last girlfriend was in college. She was clinging to me all night at a party and we just took it from there. Haven't been in a situation where an attractive woman was like that since. I left college for a job offer and left her behind to finish school. But it doesn't really bother me. I'm perfectly happy not having to deal with or worry about someone else in my life. (Much to my parent's chagrin. I'm the last of four men in my family tree and so far all I have are nieces to carry on the name.) But like I said. I'm happy and that's all that's mattered for me. I have one "best" friend who's outgoing, otherwise they probably wouldn't be in touch anymore. I tend to let people contact me or invite me out to do things and not the opposite. I'm perfectly happy sitting at home, typing away on a forum or watching whatever is on TV.
Sure, I don't fit into the "normal" work my ass off, act stupid trying to get the girl, medicated to the brim, follow all the rules model of citizen. I don't care though. It's my life and I've accepted it. The only concern I've really worried about is getting hurt while I'm alone... and I'll probably procrastinate until that happens and I'll most likely die alone. I've accepted that as my norm. Now, some of you are thinking... that's sad, pathetic, etc. I don't care. Just because I don't fit the mold of what you think is acceptable, doesn't make me feel any which way different. If anything, I have less respect for you thinking that I have to meet a set of ideals that are not my own... but that's another rant altogether.
Now, to the OP. You probably have some innate fear of such events happening. So I don't know if you are as far into the procrastination as I am, and it seems like you are trying to avoid living a life as I do, but I have to wonder if you are doing it because it's what you want to do or because it's what you are told to do.
