Sounds like you're hyperfocusing on the things that interest you such as staging plays and flatline on stuff that bores you. And there's the fear of stuff that frightens you. I'm afraid of any math beyond simple stuff; I've gotten this far in life without algebra so why do I need it now? Plus Excel does everything I need it to do .

I know for a (personal) fact that if you have the right teacher, a subject like history will come alive.

Now that I'm a job that I like, I'm afraid of looking elsewhere. I know I'm underpaid for all the stuff I do but darn it, I can make up all sorts of excuses as to why I don't look for something more. Oh...I get time off as needed for myself and my kid, I've been a federal employee for 20 years (gawd, that kills me to write that), etc. But I know I can do better. Argh!

Work on getting a proper diagnosis and if you're cool with it, try the different ADD meds that are available. One might not work but another could.
