- Comment and ask questions. Most creators are active in comments and answer thoughtful questions.
Time Investment

- One YouTube video per week: another 40+ hours.
In one year, you’ll have absorbed the equivalent of several aquarium courses – all while driving, cooking, or relaxing. The best part? The learning never stops, and the community grows with you.
