What a great answer! I have similar questions as OP in my head. Would like to have a return-on-investment on my following of technical or philisophical blogs or reading books about it. Or on what I learned about my Arduino hobby projects. But my formal education combined with practical experiences is the trick that pays the bills, even though it is often hard or boring. The rest of knowledge makes great conversations at the coffee machine or at a party.
