Welcome to the Community @William_RC!
As @JenBergren mentioned, the answer is “it depends.”
In general, I’d start with HubSpot Academy, and courses like Inbound, Inbound Marketing, Digital Marketing, and since you’re just atrating off, Revenue Operations (it’s a good one to center us all on RevOps).
I’d also look outside of HubSpot at resources like LinkedIn learning, MasterClass, and some podcasts. One of my favorite is Marketing Book Podcast with Douglas Burdett. It’s like reading a marketing book every week.
Speaking of books, are you reading some of the top marketing books? There are a lot. But I’d find some that resonate (David Meerman Scott’s New Rules of Marketing and PR is a great one, along with Mark Schaefer’s Marketing Rebellion) and dig in.
And of course, keep engaged in this Community. Lots of folks to connect with, learn from, and possibly work with!
