When I was really young, I would occasionally take over my friend's paper route when he was busy. Not being much of an early riser, I never got to eat breakfast on mornings where I delivered the paper. That, of course, was a problem that could easily be solved, if I just had a toaster on my bike.
So I made one. I had no idea what I was doing, so it worked by shorting a 9 volt battery, which created heat. The bread would get a little bit warm, and then my automatic butter melter would melt some butter on the bread. It wasn't a Dualit, and it consumed a 9 volt battery every time, but it made my substitute paper-running a little more fun.
For as long as I can remember, I knew that if something you wanted didn't exist, you built it. One of my earliest memories with my very first friend, Brian, was scheming to build a spiderman-style web slinger.
And now, of course, I still do it. My ideal blogging platform didn't exist, so I'm building it with my friend Todd. Neither did my ideal RV, so I built that, too. Then there's Cruise Sheet, the island, and any number of other things.
