I had a coaching call just now, but I felt more confused after the session.

I am working on my career change, and trying to establishing an art practice. I have done ‘Live my purpose’ course, ‘Self Confident’ and Monday Hour One. However, I am not able to evaluate my progress even though I have been in Scholars for three months now.

I was told that I need to master one thing first before moving onto the next thing, but how do I know that I master the one thing?
Should I repeat the courses again before considering moving forward to the next one?

I know that everyone is different in the Scholars, and that I need to find my own way/method, but I would really appreciate more tips on how to master one thing? To know when is the end of it? So I know how to continue this SCS journey.
Thank you.
