I found the FI(r) course one of the hardest things I have ever done (I've done quite a few hard things!)
I used to hate forced landings now I love to practise them thanks to my FIC instructor we did them nearly every flight sometimes 6 or more! until they were easy....
Flying and talkin sounds easy and is easy, doing it well is not!
I would say instructing is a really great thing, you will learn alot about yourself, other people and how to fly. The first 500 hours or year or so is very interesting and will improve you as a pilot way beyond what you could imagine.
One of the best things I have done so far. Go for it
