Whilst you might get some value in trying to learn in a structured way, I'd say you'll get much more out of it if you try to scratch your own itch. In other words, think of something you want to script, then try to learn how to do that in PowerShell. What I think you'll find if you try learning something as vast as PowerShell with a general approach is that, whilst you may pick up some decent general habits, you'll also find yourself learning a whole bunch you never use. Learning PowerShell is different from learning a conventional programming language as each use case you'll have will make use of different commands. It's like having a DSL for each use case. You'll use different commands for Active Directory management, for Azure management, for file processing, etc... As long as you know the basics you can pick up whatever is going to be most relevant for what you do.
