I think there is a lot to be said for being realistic with a job search. What CAN you do, instead of what you really, really WANT to do. People who are chronically late or disorganized are only kept around if what they do accomplish is done very well.
But I won't do business with a company which cannot get done what I need done in a reasonable manner.
That's just it. For children it's hard not being completely average and not being molded exactly the same --- but for adults it's much easier because there are many different kinds of jobs --- a job that might be boring means you need to look for another kind of job. If you can't focus on one thing but are better at multitasking, then find a job that suits your personality.
I know a woman who used the ADA and her "depression" to manipulate it so she only had to show up to work when she felt like it. Often times she claimed she was too depressed to even get out of bed for the day --- so of course didn't go into work. She held a full time job but they were lucky if she showed up 2 days a week and she'd be somehow less depressed on lighter work days and would manage to come for those.
