Entrepreneurial Booking – How do classify and how do you thinking about investing in coaching as a part of your business bookkeeping?

I often struggle in deciding how much to spend on my own coaching (I am a coach). Last year I spent more in the “education” category (which is where I put coaching) than any other expense. I love the coaching I am receiving and find that it is a great way to keep me on track with business growth. However, when I see it as the largest expense, it makes me wonder if it is too much. Can you help me think through this?
