Even freelancers, who are the owners of their time, often create their own work schedule. Most remote workers agree that it is better to focus on work first, and then completely get the job out of their heads and move on to "personal", than to constantly switch from one to another.
When you're at home, the thought of "I'm gonna do my personal work for an hour now, and work an hour longer in the evening," can get into your head. But this approach usually leads to the fact that the work and personal affairs suffer both, when, for example, you late at night with square eyes finish the next task under the dissatisfied grumbling of a spouse.
That doesn't mean we don't touch the schedule. You will inevitably retreat from it, as well as if you went to the office: banks, doctors and lawyers often take clients only during your working hours. But in general, your approach will not be affected.
But how personally your schedule should look - it is up to you to decide (if your work allows it of course). All people are different: someone as cheerful and efficient as possible at 7 am, and someone late in the evening. That's why you shouldn't copy Mark Zuckerberg's schedule, but better find one that suits you best.
