Goals for new scholar

New scholar here. I just listened to the beginner call. I understand that I need to choose a topic to work on and I’ll use my first private coaching session for this topic. My questions are: 1/ How much time should I plan for this first topic? A few weeks or several months? I suppose it depends on me, but I would like to have an approximate idea. 2/ Should I aim to follow the lesson of the month in addition to my personal goal (at least if I’m feeling interested in the topic of the month)?
Thanks for your help !
