While I agree with your list, it's not _always_ going to be 90/10. Day to day work is the opposite, 10/90, especially if you have a lot of production to get done. (then it can be 100% fun for stretches of time)

It's the feast or famine issue. When you don't have enough work, you are required to do sales to stay in business.

Do enough sales, and have enough repeat work, and you may find you have no time for sales, and may not want any more customers. It all depends on your customer base and the type of work you do.

Also, I loved repeat/consistent work from known customers because the documentation and paperwork burden plummets dramatically. Sometimes to nothing more than a phone call/email to start work, and invoice when it's done.
