We are happy, very happy, that you have joined the light side of the force, but here you are preaching to the choir. Go knock on doors and help others see the light. Oh, and sending some money to one of the thousands of FOSS projects that keep this running would be nice too.
Anyway, welcome again.

If you want to bring more people to Linux, preaching is really not a good way to do that. We are not a religion, we are not a cult. We are an enthousiastic bunch or nerds :)
Avoid behind judgemental of people that use Windows, Mac or other proprietary software. Do not talk about Linux in length when it was not solicited.
Instead, you can show how enthusiastic you are about all the cool things you are doing with your computer that happens to be running Linux!
When people around you, do make the choice to switch, of their own will, then offer your help with all the patience and understanding you have.
All the best 🐧🐧🐧
