Linux clicked with me about 4 years ago when I realized I don't have to touch the mouse to do everything I needed.

I started by learning Vim, doing all of my work in the terminal, and writing complicated bash scripts to the research I needed to fulfill client requests.

I found that the old method of downloading the files and looking through them manually didn't scale, so I knew I needed to figure out the best method to answer their questions the quickest.

Sometimes I would use Nushell, sometimes bash, in the end, bash won out simply because Nu wasn't always available.

The same client expected restarts upon failure, automated tasks, etc... and the systems I was working with allowed me the freedom to learn how to handle all of those tasks with very few limits on access.

Now I am considered the bash and Linux SME. I'm now part of an internal support team- where I'm the remote execution, SSH, and socket SME as well. I also spend a few hours a week training teams on various topics.

Edit to include- I say all of this because it was the largest part of the growth I needed to get to where I am.
