Logging the work that you do is extremely important.

An example of this is a recent event at my current workplace. The telemetry system had gone down and I was called in to repair it. This just so happened to occur on an observed holiday. I logged everything that was done that day, as well as the fix to the issue. This is important for different reasons the first being RCA meetings. Having this log allows me to have something to look back on in future meetings vs relying on memory of an event from weeks ago. A second reason is that anyone can look at this log and have an idea of what can fix the issue they are having(assuming they are experiencing an event with similar issues).
