I have a friend who decided he wanted race a circle track car. He asked an old time racer if he would help. The older fellow was more than happy. "I'll help you build a hobby stock car. It will be fun...but I'm going to give you some advice before we start. Building and racing this car will be a great time....and after a while when you want to go faster...QUIT!"
My friend raced the hobby car a couple of years...wanted to go faster...and QUIT! That is what I call good judgement...something I'm a little short on
