I think it is very important that you know a large group of people in life.
You do not have to be friends with everybody and you do not have to send everyone Christmas cards.
However, you should really try to expand your social circle to include a wide variety of human beings with different backgrounds, perspectives, and professions. Not only will this open your mind to the possibility of various belief systems and ways of life, but it really comes in handy when you have unfortunate events happen in life. For instance, last week when my heating, cooling, and air quality control system abruptly stopped working, I knew exactly who to call. I keep close contact with a local heating, cooling, and ventilation technician who I have known since high school. He was always extremely helpful when I needed some kind of indoor air temperature control device repair, installation, or advice. To this day, I know that I can call him if I ever have a breakdown with my indoor air temperature control devices or I just need some basic diagnostic and maintenance services for my HVAC. I never have to pay for emergency repair fees and I know that my HVAC equipment is receiving top-notch air quality control attention. Beyond that, my friend is extremely helpful when it comes to securing basic maintenance materials. I don’t think I have ever bought an air filter for my heating and cooling system, because my friend always gives me free HEPA filters when they receive a new shipment of filtration devices at the shop. Having a heating, cooling, and air quality control technician as a buddy is some of the best advice I can give.
