One of the first proper jobs I had, I ended up doing unofficial support for the Windows 3.1 machines that they had. I can't remember exactly what I had to do, probably just cleaning temp dirs or something, but I got regularly called to one of my friend's machines.

He liked to play minesweeper and I found that the high scores were just stored in minesweeper.ini or something. I didn't know very much about computers at the time but I could manage that [1].

So, whenever I was on his machine I would edit the file and add my own name with a score that was one second quicker than his.

He got some really good times so I feel it was definitely an encouragement to excellence!

[1] When I was in my 20s I was immortal and knew everything. Now I'm in my 50s, with decades of experience, I am very much mortal and know practically nothing. Strange how life turns out.
