Automation
Automation is one of the highest-leverage tools for running a helpdesk and maintaining systems at scale. Microsoft makes a lot of that work approachable through Entra ID, Endpoint Manager, and Azure.
The useful habit is not automating everything. It is researching the repeatable work in your environment, then choosing the smallest reliable automation that removes toil without creating a process nobody can debug.
There are plenty of forums, docs, and consultants if you get stuck. Make the most of what you already own.
