Best Practices – Study Vault

Hi, I’m a beginner with SCS and wondering about how to get the most out of the Study Vault. I love the ‘constraint’ concept and I’m wondering how to apply it. A detailed/picky question perhaps, but how exactly does that work? In other words, I decide to focus on ‘self confidence’ first and limit myself to this area of focus for Month 1? Or – is it more accurate to say – I focus on self-confidence, and then I choose to focus on ‘decision making’ for month one? How broad/narrow does one typically get each month? I’d like some guidance here based on what you all find is “best practice” here. Thank you!
