Some advice for anyone who is seriously considering a move away from Windows:

• Set your expectations appropriately. Linux is not a drop-in replacement for Windows. IMHO, it shouldn't be.
• Some things that you take for granted are not universal. Much like a new language (especially your second one) even the basics are often different.
• There is a lot to learn. If you have the patience and humility to be in kindergarten again, you'll probably do fine. If you expect to be a master quickly, you'll probably get frustrated.
• You don't have to tackle the whole learning curve all at once.
• A few notable Windows programs won't run on Linux. If you have very rigid and specific software needs, like "Photoshop is the only tool that I can use to make a living", you might consider running those in a virtual machine, or on a second system, or dual-booting. If that's too complicated for you, then you probably shouldn't try to force yourself into Linux. Maybe try again in a few years.
• There is more than one GUI (desktop environment) for Linux. Some look a bit like Windows. Some look more like MacOS. Others look like something you've never seen before. You can test drive many of them by booting from a USB "live image". In case none of them feels quite right, most can be customized. To get started, just pick one, and know that you're not married to it; you can always switch desktops later, without even reinstalling the OS. Your applications will still run.
• Investigate hardware before leaping into it. Linux supports a great many devices out of the box, and even more with a bit of configuration. If you have the means, you can buy a system pre-packaged for Linux, including drivers, just as most systems are for Windows. If not, chances are that you can still find or build a system that runs it well. Plan ahead.

For reference, there's a lot of diversity among people running Linux, from software developers to secretaries, from children to octogenarians. I imagine it's easier for kids, since they don't have as much to un-learn, but the Grandparents in my family switched to it from Windows and didn't want to go back. If they can do it, I think it's fair to say that many others can, too.
