It was already mentioned, but I'm in the GnuCash family. Moneytree to access the latest updates on my bank accounts and credit cards. I update GnuCash daily and enter each and every one of my expenses, try to budget a little bit, make sure that I reach my goals every month, etc.
It might be overkill, but I like to think that knowing exactly how much I have to the yen at any given time by simply opening GnuCash is good life hygiene.
