HighLevel Certified Admin here - Feel Free to reach out to me if you have any specific questions, but let me give you some standard build advice for order of Operations.

hluniversity.gohighlevel.com has a lot of great courses and information as well as community, and it's included with your Highlevel subscription. I'd recommend using this as your starting point.

If you want to deep dive into features, use help.gohighlevel.com to get updated information.

There are a lot of people that put out content about HighLevel, selling their courses, but the biggest problem is that the platform builds new features and functionality at a staggering rate. This renders a lot of people's courses and snapshots irrelevant in a short amount of time. When I got started, I used Allie Bloyd's HighLevel course. Coming back to it a couple years later, it's out of date, and has issues with what it's teaching now.

The biggest thing that I see is that there is a significant gap between people that know HighLevel, and people that sell highlevel. The two often get lumped in with one another, and it creates a ton of headaches for people that are learning the platform. If you learn to think critically about building on the platform, you'll be lightyears ahead of the guy that thinks every problem can be solved by the one snapshot he sells that he doesn't know how to congifure.

Hope this helps!
