It's true we all have strengths and weaknesses. Sometimes just being pushed too much can cause stress and make us preform less good. But sometimes we just suck at some stuff and excel at others. As as aspie/ADD-er I'm so so aware of this. I often fail at "simple" things. I mean I can't even drive and I'm middle aged. I just have a too slow reaction speed.

I was lucky when I was young I had teachers that actually saw my areas of talent. Or I might have thought I was a failure alltogether. If they never use or ask about your strengths, you might think they don't exist.....

Everyone doesn't have an even level of performance. Some are quite OK at "everything" and they set the norm for what people "should" be able to do (and therefore also what is extraordinary!) and some people are more uneven. If people only ask you to do what you are bad at, you will feel terrible....

I wish you were in an environment that allowed you to more focus on your strengths, maybe you have to try to create it for yourself.
