That's a really good tip, regarding a Windows or Mac user who is considering switching to Linux: instead of just jumping straight into installing Linux, keep using Windows/macOS but switch all the programs over to FOSS. Keep running Windows, but replace Chrome with Firefox, replace Windows Media Player with VLC, replace Microsoft Word with LibreOffice Writer, etc. Make it your first step to replace all the individual programs that you use on your PC with open source programs and get used to using them so that by the time you are ready to take the next step and you finally install Linux, you can just install all those same open source programs that you are used to. Those open source programs are all available on Linux as well and you know how they work, so the transition should be painless. You will still have to learn a bunch of little quirks about how Linux differs from Window/macOS, but you will save yourself from the additional headache that comes when individual programs do not work as you expect.
