On my own

There is something cool about doing your own work on your stuff. Besides just saving money, you get a deeper understanding of how the things you use work. Last weekend I did the 30,000 mile service on my bike.

This isn't really new to me now. I've been through this maybe a dozen times or so some 2007. I'm getting better at it. It seems complicated. Internal combustion engines are mysterious, right?

Not really. Once you know the principles, they're all really the same thing.

Not just that, but these things were designed to be serviced. No reason you can't do it yourself. And, like I said, you save a whole bunch of cash!
