When you get an alert for a task you need to do, its very easy to dismiss it because you “don’t feel like it” at that point in time (you have more urgent things to do, like arranging the icons on your iPhone.) It’s easy because the context of the task is lost. You forget the “big why” – why do you need to do this!
If you write the reminder in a way that would give you the context of why you want to do this, it might help you execute on it and not reschedule. Don’t write as a “floating” task: “write a new blog post about time management for kids”, instead try: “write a new post about kids time management because I need to win over the parents target market”.
