I suggest you do a financial analysis of how much you charge, what you need to make, what you want to make, and the financial goals that you have. This will give you the initial numbers that tell you how much you should work given your needs and goals. As you go on, make sure you are tracking your metrics on leads and conversions. In addition, you will want to do a cash flow analysis. All of these numbers will allow you to predict your income and the amount you need to work. Remember, this is just a simple overview. Give me a call if you have any questions.
