My first career was engineering, and I was very much linear, black and white sort of thinker.
Then I got a law degree. It took a long while and fired billions of synapses to grok the "it depends," "shades of gray" way of thinking. Both have their place.
Human motives are all over the map. Complex and also shiftable.
I had considered a law degree, but the only field I was interested in was corporate/international business. I just stuck with accounting/finance. I got my “Gray area” fix with investing.
