I've struggled a lot with having _one_ system that works. The best ones for me are either a physical notebook (Moleskine style or spiral) or a stack of index cards. What's good about index cards over a notebook is that you can lay them out so they're all visible at once, can sort them how you like, and it's easy to dispose of cards when they're used up. Digitally, I juggle Keep, Evernote and email, so no I never quite trust one system. I wish Evernote had a Keep-like dashboard where you could see multiple notes.
