How do I start building a second brain without getting overwhelmed by tools?

The trap most people fall into is thinking the system comes first. It doesn't. Patanjali teaches us that mastery begins with practice, not perfection—and your second brain is the same. Start with what's already in your hands: a notebook, a notes app, whatever. The real work isn't choosing between Obsidian and Roam; it's developing the habit of capturing what matters. Here's what I've seen work: pick one tool you already use or can access without friction. Don't optimize yet. For the first month, just write down ideas, questions, insights—anything that stops you mid-thought. Don't organize. Don't tag. Just collect. Once you have momentum (roughly 50-100 notes), patterns will emerge naturally. *Then* you can think about structure. By that point, you'll know whether you need connections, tags, or something else entirely. The psychological transformation Patanjali points toward happens through consistent practice, not setup. Your second brain grows from what you feed it regularly, not from the elegance of its architecture. Start this week. One tool. One capture habit. Everything else follows.
