You can create a new job in your current job.
You can show up differently.
You can take on different tasks and tweak the process to get them done.
You can automate your most mundane work to focus on the value-enriching work.
You can cancel that update meeting and work through whatever you were going to talk about it and send out the update in an easy-to-read update or post to the team.
You can’t change it all on the first day, but you can tweak your way to changing it until it looks completely different.
You just have to be willing to put in the time to do it.
