In 2016 I started working at a public library. Their system was a mess, they had a bunch of excel sheets and were filling the names of the books one by one, no backup, no control whatsoever. Every worker was over 50. They had zero budget and zero support and the tech team were just two guys taking care of thousands of old computers in the whole building, not just the library, they were nice but always busy, not their fault. Since I had a lot of spare time when no one was around, I noticed their computers had Visual Basic and MS Access, so I've learned SQL from zero, from scratch, and for a whole year I've worked in secret in a new way to handle our daily routine. Rainy days were the best, because people would rather stay home and I had plenty of time behind the counter without anyone around. One day, I decided it was good enough and the next day I was teaching everyone how to use it. It was so simple everyone got it, they were baffled. I also managed to organize and pull statistics for over 15 years of borrowing books, things they never even thought of questioning about their own services. The system worked for several years and it was seen as a blessing, saving everyone's time. I've got a lot of compliments, pats on the back, people loved it, but since it was public structure and my system was not the official one, then I've got no bonus for it whatsoever, as I already expected. When covid hit, the library had to be shut down and a lot of people were fired, myself included. Last year I went back there to visit my old colleagues, they said it was all working perfectly up until a couple months ago when something-something was updated and they couldn't get it to work anymore. Guess what? They went back to the old messy excel sheets, because there is no one left around to take care of this issue. I shrugged and said "not my problem". That's my story with Microsoft Visual Basic.
