This brings up memories where I wanted to do a simple project with someone else to learn about sockets in my first years of university using this guide. The idea was to create a chat MVP and improve it over time.

Funnily, the other person immediately lost motivation when I came up with a MVP on my own and wasn't much interested in understanding how the code worked.
