You don't have to be a master at the command line to take advantage of it. It's just another tool at your disposal. On Linux, unlike on Windows, we don't pretend it doesn't exist "for your own benefit". It's also not a super power by any means: some tasks are done far easier and more comfortably with a point-and-click graphical interface.
One major benefit of the command line is that you can save your commands in a text file and instruct the machine to run those commands at any given point. You can even hook up those commands to appear on the right-click context menu and run them with a mouse.
Automation is a big reason computers were created in the first place, and not taking advantage of it is like never going up to 6th gear in your car.
