New Contributer: Looking for Tips about Pacing

This is my first serious WFH job, and honestly I enjoy it. But here's some context:

• I'm working on personal projects so I don't have to put all my eggs in one basket.
• I have ADHD, so my focus waivers after some time and I need to take a break.
• I've noticed you only get paid for the amount of time you spend on task, and taking breaks during the task can potentially flag you.
  • So if I take breaks in between, that break time is not being paid.

How do you all pace yourselves while doing tasks? Also, how much time do you spend per day working in general? I suppose this is directed to the ones who are relying on this job to pay bills.
