When you decide on a new project (for yourself, not a client), what do you use to keep all your ideas in one place?
Do you plan your project out in great detail or take an Agile approach and create an MVP and let it evolve? Do you keep a document outlining features, or do you let your tests be the documentation?
I've used Trello, spreadsheets and Evernote, but I just don't seem to be organised enough to make it stick. I tend to work on a project for a few months, then break off when it's live. A few months down the line when I start to work on it again, I seem to always get a bit lost and it takes a while to get back with it.
