When you don’t have any particular emotionally charged goal(s) in mind — no time/knowledge management technique would really make a difference.
But some of them might give you a good illusion of something important going on.
And as soon as you have specific important goal in mind (like preparing to specific exam, getting lawyer license etc.) — almost any approach you feel comfortable with will do the job.
You usually dont need to review possible options in advance, the goal itself gives you hints and guides (if preparing for exam means remembering a lot of scattered facts - you’d probably end up with some anki cards on your own etc).
