Which OS did you use before Linux? Windows? Are you good with Windows? How did you learn to use Windows? Did you read any books about Windows?
A couple of months ago, I got a Windows 10 laptop at work to use for business. Well, the last Windows I used regularly was XP (I used Windows 7 a bit, too, but not much). So, I’m having a ton of trouble with the business laptop, I can’t figure out how to use it effectively. I wonder, how did you learn to use Windows and not pull your hair out? Windows is so difficult to use! Linux is so much simpler 
Well, not really. The truth is that neither Windows nor Linux are particularly difficult to use, but they are very different, so once you get used to one it’s difficult to adjust to the other. You have certain expectations and you’re used to doing things one way.
The difficult part when switching to Linux from Windows is unlearning Windows. This is why giving grandma a Linux computer to watch knitting videos on YouTube is not a problem, because she doesn’t know anything about computers. But when a Windows “power user” switches to Linux, he feels frustration because everything he knows about computers is suddenly useless to him, he is a newbie just like that hypothetical grandma. You just have to endure that frustration until you get better with Linux. It does not take a lot of time (it will take less time than it took you to get good at using Windows).
To make the process faster, I suggest stop using Windows entirely. Most importantly, do not dual boot with Windows, because every time you need to get something done, you’ll be tempted to do it on Windows. You’ll say to yourself: “I just need to edit this photo in Photoshop, it’s urgent, I have no time to mess around with GIMP now. I’ll do that later…” and the next thing you know, several months will pass without you booting up Linux. Learning can only happen outside the comfort zone, so just stick to Linux until you get comfortable with it (if that is what you want), and just accept the decrease in productivity and that doing even the simplest task will be frustrating for a few months. It will not be like that forever, and soon, Linux will feel completely natural to you.
Now, you can read books about Linux, there is no harm in that, but unless you live in Linux for at least a year, that is just theoretical knowledge that will not stick in your mind.
