I'm not driving self esteem - I'm just well equipped to say that you can't start without knowing the basics. I actually spent nearly 8 years as an engineering mentor, teaching others so I spread my knowledge. I also sit and help people but to be honest sometimes it's hopeless as they just don't have the fundamentals and aren't interested.
My problem is that the fundamentals are completely wiped out by the whole Maker movement in favour of short-cutting and getting things done, regardless of how dangerous or stupid they are.
