A Hot Rod Go-fast-soul (Go fast. Die young style, the Jesus way.)
Blind boldness. (Old testament God style)
A sense of elegance. (My inspiration here is the Holy Spirit)
Those are the 3 things you need to be a goto gearhead and mechanical mastermind.
There is just one big problem; Age.
Here's what; when you're a wild teenager with appetite for cars and bikes, to produce blind boldness is normally not a problem. It's a given factor.
If you're a natural born motorhead a hot rod go-fast-soul normally arrives effortlessly in your early 20-ties.
But style and elegance requires more experience, time and an artistic mind to develop. This comes slowly from nowhere and evolves as we're getting more mature. I don't want too precise about age here...
Another parameter is mechanical precision. When you're really young, wild and full of speed, needs and the urge to do deeds, service intervals and correct wrench torque is not on the agenda. Because you're busy having fun and making errors. Normally you don't win races based on self-made stuff at this age. You're imortal as can be and powerful, but you ain't got no money. Which is good.
But at some point it's time to stop thinking and just feel comfortable no matter age and personal development...since we have turbos and superchargers for all that wants to go fast and make fun last.
