If you had to restart SEO from scratch with only 30 minutes a day, what would you focus on?

I've been thinking about this recently. There's so much SEO advice out there that it's easy to end up spending hours learning and still not know what actually deserves your attention first. If I suddenly had to start over from zero and could only dedicate around 30 minutes a day, I'd probably focus on a very small number of activities rather than trying to do everything at once. I'm curious how other people would approach it. If you were starting from scratch today with limited time, what would your first few weeks look like? Would you spend that time on content, keyword research, technical fixes, link building, or something else entirely? Interested in hearing what people would prioritize when time is the biggest constraint.
