Yes do it. Having any extra knowledge can only be a good thing. I'm probably a bit odd but I find flying on instruments quite relaxing. Also one of the best and big grin parts of aviation IMO is breaking through a miserable overcast and rain into a brilliant blue sky with a dazzling white carpet of cloud beneath you as far as the eye can see, with rarely any company because the big jets are way above you and most other folk are plodding through the murk beneath you.
But then we all get different things out of flying and I understand folk who aren't interested in that side of things.
