As a SharePoint evangelist one needs to be mindful of the following:
SharePoint Growth – One has to mindful that as more users and information expands into SharePoint, the environment needs to accommodate such growth.
New Initiatives – Keep-up on new features and functionality to turn on, document and educate on.
Responding to Challenges – Work on finding the best technology to solve the right problem.
Advice – Have documentation on what tool to utilize and provide quick guides on the best use of those tools. Example: MS-Forms for surveys, Power Automate for workflow and PowerBI for analytics display, etc.
