It really pays to have a useful skill under your belt in this modern world.
You never know when you might be able to impress somebody with your inherent skills and knowledge.
It’s very possible to save yourself a lot of trouble if you can scratch somebody’s back with your expert-level knowledge of common human problems. For instance, if you know how to diagnose and repair car issues… There’s a good chance that you’ll be able to trade this mechanical service for something that could benefit your own life. Recently, I found out that my old heating, cooling, and air quality control skills could easily be leveraged to get myself out of trouble. Having worked as an HVAC tech for a few years, I was familiar with the drama of a broken heating and cooling system… but I never imagined that my HVAC skills would be so lucrative and convenient. The trouble all started when I went out drinking with a few of my friends and things got a bit rowdy. One thing led to another and I found myself arrested at the local police department for disorderly conduct. Luckily, while I was sitting in the drunk tank I noticed that the indoor air quality was suffering. Since I had nothing else to do, I stood up and started examining the air vent that led to the cell. Pretty soon, I had diagnosed the central cooling system from my tiny prison. I started telling of the cops that they needed to change their air filter and adjust several components of the air conditioning system if they wanted to improve their air quality. One free HVAC repair later, they let me walk right out of the jail. Consider HVAC repair my get out of jail free card.
