I think much depends on how knowledge gets imparted, My second motor bike came as a bitza for £30 in a couple of orange box's, I asked my bro for help he said "sure", put down a tool box and a manual and said "there you go" and just grinned, this was very much how my step father passed skills, and would only step in when really needed, my bro only helped again to get it started, they both imparted the best thing of all, self reliance and if you don't quit you can make the unknown known and you only fail if you don't stay the course.
