The expression “jack of all trades, master of none” implies someone who knows a little bit about a lot of things, but knows a lot about nothing, however i have never been sure if this was supposed to be an insult or not, because I am not sure which a single is better.
Is it better to have a broad general knowledge of several things, or a deep insightful knowledge of a single thing? As it comes to pass, I ended up focusing my brain on a single small area, and it actually has paid off for me.
I have been able to parlay my extensive insight into ventilation systems into a specialist task for a major Heating as well as Air Conditioning corporation, and have been making unquestionably nice money. I have to travel a lot, which I could do separate from, to do location visits to sites with unsolvable ventilation and Heating as well as Air Conditioning troubles. That is what I do, I am the last resort that people can call when they cannot solve a problem involving air ventilation; Usually I only get called in for laboratories, hospitals, or other sites were ventilation and air circulation can be a matter of life and death. Ventilation is the exchange of air, moving terrible air out and nice air end, but when the terrible air is toxic moving it “out” can pose a challenge. I do care about my work, and I prefer the problem-solving nature of my tasks, so in my case specializing in ventilation and Heating as well as Air Conditioning systems has unquestionably much paid off. I am a master of the ventilation trade, and jack of none.
