1. What was the advice:
There's a lot, but probably creating SOPs
2. Why didn't you listen
I was doing all the work myself and knew how to do it all so I assumed that it would be really easy to do once I needed them.
3. What changed your mind
When working on more complicated tasks, I realized I would forget how to do some parts the way I wanted (such as the various Sheet functions I needed to add or how to format the document) AND when I was WAY overloaded with work but couldn't pass off relatively simple tasks as I didn't have training on how to do it and didn't have the time to make it.
4. How has it helped you
It's something I'm still working on, but I've gotten a lot better at creating videos quickly that a VA can understand as well as recognizing when I'm doing a task that I could spend 10m on a video and send to a VA to save myself 4-5 hours of work. Some weeks, saving me on 20+ hours of work.
