I try to remember the quote, "...for there is nothing either good or bad, but thinking makes it so" from Shakespeare's Hamlet.
I had a terrible sports injury, damage to the cartilage in my left knee a few years back. Left me not able to do a great many things I used to, and I have to be cautious on all the rest. I've got to stretch 10 minutes a day or my leg starts hurting. For a while, I could barely walk - I was taking industrial-strength doses of anti-inflammatories and doing physical therapy, icing my leg nightly.
For a while, I called the few minutes I hurt my leg "the worst 10 minutes of my life", because it seemed to be massively inconvenient and painful on a long term basis, with absolutely no gain whatsoever.
And yet, somehow, I took a great many lessons from it with time. I do everything slower and more deliberately now, I pay close attention to my health, I floss, I take care of my back. A bit embarassing to say so, but it severely limited what I could do in the bedroom - but the irony is, it made me a better lover. I lost all variety, because any position that came from weight on my knees I couldn't do for more than a minute of a time. All the strength and power had to come from my arms, shoulders, and maybe a touch from my hips. But losing all variety, and being limited to just a couple ways of making love - it gave me an immense amount of practice and forced me to think really critically. I'd say I'm probably a better lover now, injured, than I ever was before fully healthy.
Ironic huh? IQ clearly has a lot of benefits, but sure, a lot of downsides too. In the end, it's what you make of it and how you think of it. Here's the scene from Hamlet:

Hamlet:
What have you, my good friends, deserv'd at the hands of
Fortune, that she sends you to prison hither?
Guildenstern:
Prison, my lord?
Hamlet:
Denmark's a prison.
Rosencrantz:
Then is the world one.
Hamlet:
A goodly one, in which there are many confines, wards, and
dungeons, Denmark being one o' th' worst.
Rosencrantz:
We think not so, my lord.
Hamlet:
Why then 'tis none to you; for there is nothing either good or bad, but thinking makes it so. To me it is a prison.
