I'm still having a hard time seeing this as a debilitating condition, I can relate to all the things you said and undoubtably taking drugs like modafinil or ritalin turn me super productive and focused, but I don't want to be medicating day in day out, tolerance grows too fast.
End of the day responsibilities forced me to stick with things after I lose interest, sure I may be 20% as productive as I would be if I was super interested and I spend 80% of the time distracted because I'm bored, but 100% is usually 5x of what people consider the norm anyway.
