Thank you for the kind words. It's a bit of both. I do enjoy working with machinery but it's really a matter of necessity that I do it so much. I save myself more money than I could make given the amount of time I invest in these projects. For example, I saved somewhere between three and five thousand dollars by replacing the engine in my car myself. I currently have no other way I could make that kind of money in a weekend, and I already have the expertise required to do the job, therefore it's well worth my time.
