Below are some prompts and exercises to help you find more knowledge.
Review
What specifically don't you know how to do yet? Get as specific as possible. “I don't know how to start a business” is too broad. What exactly is missing?
Do you need to learn it yourself? Could you hire someone, ask someone, collaborate with someone, use a tool, or find an existing solution instead?
How do you learn best? Do you need to read about something, watch someone do it, have someone explain it, experiment yourself, or learn through trial and error?
Who already knows what you need to know? Think beyond formal experts. Friends, former colleagues, people in your community, people online, people who have simply done the thing before.
What are you afraid will happen if you don't know what you're doing? Are you worried about making a mistake, looking inexperienced, wasting time or money, disappointing someone, or something else?
Practice
Build Your Own Curriculum : choose one thing you want to learn and pretend you’re designing a university course around it. Give yourself a semester. What would you need to learn? Break it into 4–6 “modules” and decide what you’ll use to learn each one (books, videos, courses, people, experiments, whatever works). Give yourself assignments and a final project. Book the “classes” into your weekly schedule.
Beginner Mode: pick something you've been intimidated to learn and give yourself one hour to be a complete beginner. Make the thing, attempt the skill, or solve the problem without worrying about being good at it.
Source Hunt: choose one thing you want to learn. Find five different places you could learn it - a book, course, person, community, podcast, YouTube channel, university, workshop, etc. Compare them. Which is best for what you need right now? Map them out into two categories: what you can currently access and what you can build access to.
