If you struggle to schedule, which you don't seem to, you can de-schedule.
What I do is schedule time for goofing off (browsing) that way the rest of the time is focused on what I have to do. Granted it helps listing the tasks but I struggle to complete tasks in allotted time frames.
I tend to schedule more time than I think I'll need to complete a task, rather than less. Any time left over goes to tasks that I didn't complete earlier in the day and, if none exist, I browse.
