Honestly, I don’t think people can or should be convinced. If you dislike Windows(/Mac) for whatever reason, the first step is to find multi-platform applications and attempt to switch to them (if possible) on your current OS to lower the friction of switching as much as possible (also more free/less bloated is good too). For instance, Krita is a nice application and it doesn’t matter if you’re on Windows or Linux. Many things you use (or may know about already) may be multiplatform (browsers, Blender, indie games etc).

After* that, I’d say test it out. Such as a liveCD, in a VM, on a Rasperry Pi, on an old computer, on your next computer (if it doesn’t have an OS pre-installed, such as DIY builds). Or if you have a desktop and a spare drive, you can even remove your Windows drive so you don’t accidentally wipe it. Just remember to keep in mind that each test method has its own limitations (as in Linux on an some of these options will not be as snappy as a real install on a newer SSD). You might want to try different distros or use it for a long time together if something is still holding you back (especially for work/school).

*= Well, depending on how comfortable and interested you are already. You might want to try it a bit before you decide it’s worth the time/effort of trying new new software with the intent of changing your workflow.
