While the economics of renting make sense from a pure "bean counter" perspective, there are reasons why we own.
A lot of us put in our time with rentals early in our flying careers. Give it time and keep your eye on the goal!
Flying and airplane ownership have had a big influence on a lot of my decisions throughout my life. Decisions such as my career, it had to pay well enough for me to be able to afford flying, and where I bought my house were influenced by my dream of flight.
If you want it bad enough, you'll find a way to make it happen, eventually.
