Waited till the trolls left. Specifically, (1) Negotiating pay, and (2) budgeting. I contend that those I worked for profited heavily from my work, therefore I'm good at my job.
Ever take Serway's College Physics (CP) /PSE/POP? Did you end up buying the study guide? If so, why did you pick that study guide to buy? I did the page layout, the formatting, all the artwork, some rewriting, etc. A lot of what went into that was what I put into it. My customer's contact (Saunders/Harcourt) mentioned that I was the best at this, that she was aware of.
For a long time, that particular text was the top seller in the world -- no credit to me, all credit to others on that one. However, the study guide is typically a major money-maker.
Jump ahead to a career change, into prestressed concrete. The last place I worked -- where I was told to put a subordinate in a brakeless water truck, and asked "are the brakes fixed?", and was told that I had no right to ask that question... and subsequently fired in great betrayal, I was still later told that I was the best field engineer he ever knew, by the guy who betrayed me.
Now, I did get another job, nearby, at the same wage, doing the same thing, and was subsequently promoted to project manager. But I can say that it isn't that I suck at my job.
But I am not free to move. And I do suck at negotiating pay. But that is not just cause for a top performer to receive bottom pay; and I have seen enough other evidence that college degrees no longer pay off, that I do not intend to send my kid to college. Moreover, I have seen the colleges fail miserably at their primary mandate, and I don't intend to support that either.
I have told my kids, that they need to work at school such that they *could* go to college if they want to. But if they want a further education they should forget the degree, and just find out what the courses are, get the books, work through every single problem, try the stuff out themselves. If they still want a college degree, they should do 2 years of tech school, 2 years of work, 2 years of community college, 2 years of work, 2 years of university, and then they *might* have a chance of getting a job. But I'm not going to send them to that, because I don't consider it to be an idea that is likely to pay off.
At this point, my advice is more along the lines of agricultural and Christianity. Forget business and tech -- in our society's glorification of "greed is good/more for me, none for you", it made too much use of an empty promises.
