Mind maps rock! How many of your ideas are completely linear? How many parts of those ideas do you need to think about in depth? Our minds are crazy good at intuiting nested and complex data but not so good at understanding it, so it’s really easy to get in the weeds with a complex idea and struggle to connect the parts.
That’s where mind maps come in. Their super loose format allows you to tie things together spatially and grow that structure organically. I have been building these structures in all kinds of ways for years, but with a whiteboard notebook where I can move a node with a finger swipe, it's really powerful. Then to be able to scan the map with an app and actually be able to find it later? Awesome.
