Hi, welcome! So my first suggestion is to go to the “Case Studies” subtopic - there is a template there you can fill out that can help you provide a little more detail. It sounds like even filling out that template might be really useful, because it forces you to pay attention to where your money is going. So do the best you can now, and then flesh out with more detail as you get it.
Which brings me to: track your spending. Every penny! Don’t worry, it’s not as hard as it sounds - there are several programs like Mint and You Need a Budget that make it very easy to enter things as you buy them. This is really really critical; I know it doesn’t sound fun, but when you just don’t know why the money always seems to fly away, the first step is watching where the money flies away to! The great news is that once you do this for a month or two, you will probably be horrified by the amount you spend on stuff that wasn’t worth it (I can tell you for a fact that this will happen, because if you don’t know where the money is going, that means that whatever you spent it on wasn’t memorable). And that will help you decide for yourself that you can cut XYZ and not even miss it.
Finally, while you are getting your ducks in a row, read the forums. There are a lot of people here with really awesome ideas and tons of experience, and they can be very generous with their time helping people who aren’t as far along the path. I would particularly encourage you to read and even join one of the challenges in the “Throw Down the Gauntlet” forum. I personally am in the grocery spend challenge, because I got very lazy and was spending way too much, and again, the people there have great ideas and are very supportive to people who don’t do as well as they do but are trying.
Good luck! You made a very good call joining here, so welcome aboard!
