It's hard to be 100% with these things, but saying "no" to bad practices even once is an improvement over nothing, so keep that in mind.

We are also creatures of habit, so I would encourage you to try to challenge yourself into using the things you'd like to be using for a longer while to see if it sticks. For me, this was easy, because I was forced into daily driving Linux and so on for years due to just not having the budget for the newest Apple products or whatever, and when someone gave me a newer computer that came with Windows 8 or something, I didn't find any real use for it and it kept gathering dust until I installed Linux on it too.

And because social circles are really important too, I think you'll find it really encouraging to hear that due to my "dedication" to this matter, almost everyone I care about has actually already followed me to alternatives like Matrix, so I can contact almost everyone with E2EE these days! :)

If you still find yourself feeling limited after something like that, I think if I were in your situation, I might consider running Windows inside Qubes OS or something, though maybe not for gaming due to the performance costs associated with virtualization.
