Tips for being a good BSD system administrator

The biggest thing is having some sort of centralized place to store documentation about what you're doing and how you're doing it. I personally, am using Obsidian for it, but there are a bunch of other tools.

I'd also strongly recommend learning a bit about grep, sed, awk, xargs and a some basic shell scripting. Even without spending large amounts of time on it, just learning the bits that relate to what you're doing is a significant help in terms of efficiently managing the system.

I also think that it's worth setting up a virtualized system where you can easily back out screw ups you make and don't have to worry about messing things up.

And lastly, it's worth spending some time learning a revision control system so that you can back out any mistakes you make with configuration files as you go.
 
Make written plans for your changes, and, where possible submit them for peer review.

For something complex, I would suggest ordering the steps, documenting the logic behind each step, and writing down the exact set of commands required to complete each step.

Document the steps or tests and approvals required to assert success.

Your plan should always include the steps required for reversion.

Where the changes present significant risk, test your plans before executing them on production systems.

Review your plans after the action has been completed, and store the (amended) plan for future use, making it available to those who may follow (which includes yourself).
 
no matter which way you do it, try to document everything (every install, every change to a system, every failed experiment). And make sure these notes are available to you.

I keep mine in a static blog (they are just notes, there are no secrets in there, so I don't mind if other people look at them), but other ways have already been suggested in this thread.

There are, but I personally find in practice having a more organized approach to what you're taking on makes a huge difference. Most of that comes from all the things that you can do, but don't necessarily need to do. I just found out that you can put bhyve in a jail. I hadn't even considered doing that.
