Get clear on how much you're bringing in and how much is going out in your business. I like a Google Spreadsheet to keep track of my business expenses (that I then use for my tax expenses). Set time to review it every week or month.
I like hourly time blocking! I list out everything I HAVE to do--in my day job, my business, my appointments, my workouts etc. If it's not planned in, it's not happening most likely OR it will take me way longer to do it because it's not planned in. Find a system that works for you. If you haven't checked out my free training on getting back 5 hours in your week now, grab it here.
