I've got a family member who always has to have the latest technology. They love having all the latest stuff. You know this guy, too. They're in every family or circle of friends. Must be nice to have all that money!
I also have a friend who can MacGuyver anything. Give him some paper, a safety pin and some silly putty and he can make you a ham radio. Odds are that you were in one of those guys' garages or basements recently.
Successful slot car racers tend to be a combination of all three of these traits. Some tools in your slot box are probably from when you first started in the hobby, but the tires have silicone developed just last year. You've honed your skills on tracks throughout the region, state and country. You saw that cool thing that other racer did or had, but didn't have the cash to get one so you made one yourself. You should be proud of yourself. You're a talented high-tech MacGuyver.
Through the combination and application of these three ingredients, we can all become successful when we apply ourselves.
Oh yeah, and then there's that lucky friend...
