If you have no idea what type of inputs you should be doing, ask yourself this question:
"How can I get my next/more appointments or sales?"
Every input you do should be aimed towards getting more money, in business terminology, getting more appointments and sales.
The first things that come to my mind are doing outreach, posting content, upgrading your offer, running ads... learning should be the last of these inputs. If you did everything you can think of you can do that day to get new customers, you can spend your time on learning.
Action and experience are the 2 best teachers there are, better than any course or any guru going over a subject on youtube or in a book.
