Ok. I’ll play. In a past life I knew quite a lot about excavators and mobile cranes A colleague knew a lot about printing presses and another knew about CNC machines None of us had technical knowledge - it wasn’t relevant. We knew the sellers, the buyers and the valuers. We also got to know - largely through painful experience- the crooks and scams in the industries But here is the thing. Whilst there were similarities, the knowledge we each had was sector specific and wasn’t interchangeable If you go out and decide to be a generalist in ‘heavy equipment’ you will get very, very badly burnt. .
