Would I really enjoy Jannah [paradise], if at all I manage to get there?

So I am just a run of the mill guy who makes a decent living. I don't expect to go to Jannah unless I mend my ways, and Allah forgives me. However, I am kinda confused if I would enjoy Jannah. I love science, research learning new stuff and fixing things around me. I always need something to work on to give me a sense of purpose and fulfillment. If Jannah is perfect then this place doesn't need any fixing or evolution and there's no sense of purpose other than indulging in hedonistic pursuits. I may not be exactly following the Koran/Hadiths but I've a lot of empathy in me. The realization that people are being tortured and burnt in hell would disturb me and Jannah wouldn't be that much fun any more. Does everyone who go to Jannah love being there? People in Jannah are of great moral character, don't they feel distress at what's going on in Jahannam.
