Welcome, I agree for the most part w/ walks,tramp & joe. But "necessity is the mother of invention" so let him make some mistakes and possibly overcome some inherant problem in a clever way. And VOILA! you've invented Thneeds or doohickies or widgets!
Failure Can Be Fun!
For example: I ate a chain yesterday when it derailed off my rear sprocket. I wasn't thrilled but I hated the stock drive from go. So heres an opportunity to find or MAKE some sort of thingamajiggi that not only fixes it but makes it better.
Failing Can Be Fun, and sometimes I gotta get mine!
