Efficiently wielding weapons is not terribly difficult. It just takes practice. My parents bought a number of guns and became quite proficient at firing them accurately within 2 years.

I have many relatives and friends who are amazing at skiing. My cousin posts pictures every winter of the sick lines he skis down.

I'm neither an excellent marksman nor skier, but I don't think it would be difficult to become excellent at both given an excessive amount of free time within a few years.

I can though drive a manual very well, own a sports car, and have no fear of drifting it.

A coworker of mine was a pro skydiver, and recommended it to everyone. I've met other skydivers as well; it's supposedly easy and affordable.

Another coworker owned his own plane. Planes are costly but he wasn't James Bond rich...

My brother-in-law owns a few hundred guns including fully automatic weapons.

Being James Bond is a bit idiotic in real life as he engages in a lot of high risk stuff, but it is certainly doable.
