I think one of the more tangible elements of tracking my progress while being a coding beginner is tracking how my habits have changed in the most basic ways as I use my computer. My experience interacting with the UI of my computer has completely shifted relatively quickly.
Previously, I, like many users, adhered to the user experience of manually clicking through folders, dragging and dropping documents and folders, right clicking for copying and deleting materials, double clicking to open files etc. etc. I stuck with the GUI.
Everything has shifted after discovering the terminal and learning some very basic bash commands.
Instead of clicking through folders and scrolling manually, I navigate through my file structures just using change directory command and using the "ls" bash command to see what files I'm looking for:
Using the command line for navigation has really streamlined my workflow. I end up memorizing file and path names (or at least what they start with), and I spend far less time navigating and resizing menus.
The bash shell seems to be a really powerful tool with a lot of capabilities I've barely begun to scratch the surface of - after all, it's not just for navigation.
You don't need to learn at least one new language every year to be a "good" programmer. The best programmers see the bigger picture and prioritize what they learn so that they can deliver the best possible results.
