There is only one tip for you: if you are not programming, you are going to suck. I have never met very good sysadmin which wasn't programmer at one point. I am not talking about hard core programming involving serious patterns, DI, migrations etc. But most of the time, you should be writing good, resilient, scripts in more serious shell language such as PowerShell. If you don't do that, your actions are not reproducible and thus your output is prone to interpretations (i.e. it sucks). Plus, there is no such thing in enterprise as one-time-tasks - if you don't script your task you will have to manually repeat it sooner or later and that is extremely inefficient and error prone.
