Why is hovering a helicopter compared to balancing yourself while standing on a large beach ball?
Helicopters are generally designed so that pilots sit on the right side of the aircraft and they can keep their right hand on the cyclic at all times.
Adjusting one flight control on a helicopter almost always has an effect that requires an adjustment of the other controls.
The radios and engine controls are free for the left hand of the pilot (usually the weaker hand).
Helicopters are very unstable.
