Trying to fit in is not nesscessarily a bad thing. People have problems all round, but if you've AS then you're pretty much fucked if you don't try.
Up to a certain point no - but we are never going to entirely fit in. The only way around the system is to find a niche which you can either control or easily adapt to. Still in those cases you are only fitting in that small environment, not in general.
If anyone is under the illusion that the more harder they work at fitting in, the easier their life will become is sadly mistaken. The problem is that the more you do, the more that is expected of you. When you get up to a certain point, you are working too hard for diminishing returns. Fitting in entirely for extended periods would drive most of us insane for those very reasons.
This condition is nothing special, it does not make you any way "better" than others. The reason why we're good at our interests is because we basically spend a good chunk of our times at it. Any retard with enough attention span on a certain hobby etc. can do the same. Don't kid yourself that you're somewhat intelligent, the hard fact is that you're not. We ARE technically NTs with a lable for shitty social skills, nothing more, nothing less.
Shitty social skills has its advantages, for one it makes you more likely to ask questions. A small thing which I say gets greatly underestimated at times. Then of course you ignore some of the things that certain Aspies have most likely have done. We could do extremely well, if only given the opportunity. For most of us, that opportunity never arrives.
