Are you a morning person? Some people work better in the mornings and some are more effective later in the day. What’s your best time?
Also consider your household. What’s the normal routine? Does the postman always knock the door around 10am or do the kids come home mid afternoon?
Working for yourself means that you can be flexible enough to schedule your day around your most effective times. If your concentration is better in the mornings, use that time to work on projects that require concentration. If you know you will be interrupted at certain times, use those times to complete low concentration or quick tasks.
