I probably would not fly. If for some reason I were to lose consciousness while in the air, I would prefer not to plummet hundreds of feet to my death and not even know it.
And, knowing me, it would be inevitable that I'd collide with a bird at some point.
I could definetly get to places a lot faster. It's really frustrating when you're late and you're stuck in a traffic jam. It would also be useful to relax. I could easily imagine myself up there watching a sunset.
Assuming I can fly reasonably fast without getting too tired.
First I'd make a world tour, getting to my destinations by flying. For two reasons: one, I get to see the world without spending money and waiting time with planes and the like. Second, I get known around the globe. Second thing, as soon as I'm back, I'll engage a marketing guy who, thanks to the fact that after my world tour I'm a global attraction, will make my (and his) fortune. Third thing, live a life in luxury, do a lot of fun things, fly a lot. Fourth thing, develop a flying suit that enables me to fly around in high atmosphere and even in space, with enough place for supplies so I can pay a visit to the moon. Fifth thing, after not being able to cope with all the paparazzi and attention anymore, bored by life on earth and surrendering to the sweet melancholic whisper of Space, I'd suicide by flying into space with my suit as far as my forces and ressources go, and die a lonely and silent death.
If you could fly, then you probably use no muscles, so you wouldn't be tired at all.
Yes, but where does the impulse come from? Should we just ignore it and assume we're giving the necessary energy somhow, for the sake of answering the question?
Also wanted to add that when flying into space I'd probably sing 'The Sound Of Silence' by Simon&Garfunkel, all the time...
