I spent a lot of time setting up firefly-iii, a really neat and feature-rich finance manager. It's a really great piece of software by a very responsive and friendly dev but after about 6 weeks I still couldn't get used to it and ended up going back to paying for YNAB.
I swear by memos now though - highly recommended. It's like having a private twitter stream where you can send thoughts, notes and files that you want to store/refer back to.
