Beginner's Guide | Salesforce Trailblazer Community

Looking for references on YouTube that might help give a more thorough visual into how one might start understanding Salesforce, while not having a business model of any kind to build off of?

I have been doing much research to find a video that might explain from a teaching perspective the what’s, how’s and why’s behind beginning a career in Marketing through Salesforce, and have struggled to find a current (or recently released at minimum) creator that might have such content.

If anyone has any leads or recommendations I would love to check them out! Much please and thank you in advance!
