What do/did you do for a living?


With the increasingly high priced items people own and are selling, I'm curious about the line of work people do or have done. I thought my $5k integrated was a massive investment, but seeing users searching for $100k speakers or $75k SET amplifiers has me curious about the varying lines of work people do to afford these items.

At age 64 , I realized I can shuffle  a few things around  in my business and make a $1k a day  working only 4 to 5 hours a day .Only problem is , I only have work for about 12 days a month.That's pest control for you , been good to me .Also have  1 Airbnb and two long term rentals that bring in about $5k a month .Do the math :)I know this thread is " what do you do" and not "what do you make ".I had to shuffle things when my only employee of 12 years died in Feb .So , now I am semi retired
Last year , sold my motorcycle  and bought hifi stuff right when my hearing loss happened , lost 5% , I guess .  Ringing in the ears , hissing and other sounds
I've had my own small business since 2009. I'm in the industry of destroying peoples lives. Not really but often it feels like it. I'm a process server. I get summons and complaints, subpoenas etc. usually from law offices and I serve the paper on businesses, entities or individuals. I like making my own hours. I like that I created it from nothing. I don't like impatient and demanding lawyers. I also don't like serving divorce papers. I hate it, but a client is a client and more often than not it's already been discussed between the parties. When it hasn't and I'm a surprise...that is awful.

1972 started working in an audio/home appliance store. 1985 left the audio business to work for a maintenance company in Section 8 housing.  1990 I began working for a local school system as an engineer.  I got my degree in Electrical-Mechanical engineering in 1977 while working part time at Audio Store.  In 1995 the School Committee eliminated all the engineer jobs and being in the union, bid on a job as head custodian at the elementary school I went to school in as a child.  I stayed there until my retirement in 2017.

During all that time, went through a lot of audio equipment, some good and some bad.  When I retired, I had 2 very nice systems.   I cashed out all my accumulated sick and vacation time over the course of my 27 years with the school system upon retirement and spent about 30K of it on finalizing my 2 systems.  I am very happily retired with my wife who also retired in 2017, house and cars are paid for and we are living the good life although we are a bit more careful with our money now. Thank God we both have good pensions and Social Security.
