I left Win8 to go full time on Linux. For several years before this, I used to host web sites professionally and build them so I was used to Centos and Debian servers but not comfortable enough to be able to manage them deeply. In other words, just enough to make them work, but more complex troubleshooting was not my strong suit.
I later landed a job where their primary systems are Linux based and through that training and learning, I became more comfortable in the CLI and have never looked back.
