When I moved into my new house at the end of September, I took on a lot of new financial responsibility that I've never dealt with before (mortgage, monthly utility payments, outstanding debt on large purchases, etc). As such, I've been a little overwhelmed in trying to keep up with what payments I've made and, more importantly, where my money is going each month. In short, I want to track my money.

There are a number of avenues I've briefly explored, some of which require a lot more effort than I think I'm willing to exert. Mint.com looks really interesting, and looks a lot like what I want, but I'm leery of giving out my banking and credit card information to a third party. The same can be said for Quicken Online. Non-web software solutions are a possibility, but obviously restrict my ability to view the data from anywhere. They also often require more manual input than their online counterparts.

How do you keep track of your money? Do you have a tried and true means of seeing where you spend? How do you keep track of what bills have been paid? Any tips from you seasoned veterans would be helpful for a newbie like me.
