You can totally do this. What's the alternative? Also, one weird thing about money is that it responds to the attention you pay to it. So, if you start budgeting and allocating and responding when you make mistakes (because you will), in a few months, you'll actually be further ahead than you think you can accomplish. I don't know why that is, but we are seeing it in our budget. Now, sometimes surprises happen too, but that is life. Let us know where you are in 3 months and in 6 months. You'll be surpised.
