Keep things simple
A useful notebook needs very little: a clear title, a few honest sentences, and enough space for an idea to change. Small observations are often the ones worth keeping.
Make time to read
Reading slowly makes room for connections. Write down a question, return to a paragraph, and let the next book be a conversation with the last.
Build with care
Good tools stay understandable. Start with a small working version, test it in the real world, and improve the details that matter.
