Bn, Tractor makes a very good point, “But it would be a heck of a lot more fun,” and you have a valid point, eg; return on investment. Owning an aircraft and properly maintaining it is a costly adventure. Unfortunately, many people get the bug to fly and buy an aircraft only to let it set at some airfield and rust away. The only way you are going to know if this is what you want to do, is to do it. You will know early on if flying is for you and eventually decide if aircraft ownership is for you.
To me, there is no place I am happier than in the air, whether it be on a demanding, [past tense] CAT III approach to an unfamiliar airport, screaming earthward at Mach +1, or lazing around the clouds in the Citabria. Take the step and give it a try, you may be surprised.
