Quiet week. Still holding, no new position.
Why not just use a spreadsheet, or a note app?
A spreadsheet makes you design columns before you've written a word. This has none — just a date and a sentence.
A note app or tracker has opinions about what matters — numbers, checkboxes, charts. This has zero fields. It's for the thought, not the metric.
And you're not limited to one. Keep a journal for your portfolio, one for your health, one for a home project — switch between them from a single dropdown, right next to each other. No separate files to juggle, no separate apps to open.
Inspired by Derek Sivers
Derek Sivers has written for years about keeping a daily diary and separate "Thoughts On" journals for every subject he keeps coming back to — as plain text files. It's a great system. This is that same idea, with the friction that stops most people from actually doing it sanded off — and a PDF export any time you want a plain, portable copy outside the cloud, same as he'd recommend.
