Finder Not Showing User Library Folder

Note: The Library folder has been hidden since Mac OS X 10.7 Lion, I believe, and the following method works for Mac OS X 10.7 up to macOS 10.14 Mojave.

While in a Finder window, navigate and select the “Go” menu on the menu bar (upper left), hold down the option key and the “Library” folder will show up. Select it and Finder will take you to that folder.

Here’s a neat video by Shani Jaf who explains in more detail and other ways to get to the Library folder:
