I don’t know about everyone else, but I had a lot more spare time to tinker with linux when I was a student than after, having a full time job. But I guess if you only have the one computer and need it to work, then tinker in a VM or something. Don’t wait with tinkering and learning about linux if it is interresting to you and something you want to spend time on. You might not have the time for it in a few years.
