TLDR:
Skill of asking the right questions
Skill of problem solving
.............
I disagree.
Learning how to follow a recipe is a skill. Trust me there are plenty that cannot.
Dictionary says something like skill = a learned power of doing something competently
Is using Google effectively a skill? I think so. Any one can use Google, but can they ask the questions in such a ways they get the right answers and are they able to quickly filter out the dross.
So I would say a useful skill in starting a business is the ability to ask the right questions of the right people ( or search engine ) so you can bootstrap your knowledge.
@fisicx you didn't know how to set up your limited company online by osmosis did you, you either asked someone like your accountant, or on here, or read a book or article, or put a question into a search engine and read something.
Another skill is problem solving. This is something that you learn and improve on, there is a process to problem solving and again many have no idea how to do it. I do it so much I forget it is a learned skill and just think it is a natural ability.
I'm often asked to fix complex technical things by friends, family, colleagues and often people say things like 'I really must learn more about technology' and my answer is 'Do you really think I know everything about technology, I knew nothing about your problem, but I know how to solve problems, what you need to do is learn how to problem solve'.
