Is this because you think it won’t take as long as it does or because you get distracted during the pomodoro?

Because things always take longer. "Finish this feature" is scheduled at 2 pomos but in hindsight really needs 20. So then I have a choice to blow through my carefully arranged schedule and finish things, or leave work hanging. Haven't solved this one yet.

I just have one priority and keep working on it until its finished or something else become the priority.
