That's a really interesting question, BB - especially considering the fact that I eventually intend on doing this for a career. Is it something that I will enjoy doing?
Well... yes... but I wouldn't say that's it's fun in the same way as like, say, a roller-coaster is fun. Like it's not, "Wheee... I'm flying!" It's more a combination of both relaxation and exhilaration at the same time.
There is definitely a "zen" thing going on, as the controls are so sensitive that you pretty much just need to think what you want to do and the slight movement that naturally occurs as a result makes that change happen. But, at the same time, I would be lying if I didn't say that - at least at the beginner level I'm at - it takes a lot of focus to achieve that. On the days where it's nothing but hover practice, I've definitely worked up a sweat by trying to be too intensely in control.
So, yeah... it's a bit paradoxical. Up at higher altitudes, sort of cruising, it's more chill and you get a bit of time to just marvel at things... while in a tight hover at ground level you are doing so many things at once that - upon refection later on - you feel a real sense of accomplishment.
I wouldn't really call it fun, but I do love doing it. I think, in this activity, I've found my "bliss".
