Battling with the Clock

I know many time management strategies.  Why is it that I find so many of them difficult to implement?  I'm a calendar person.  If it's on my calendar, most of the time, I can get the task complete.  But recently, I find myself also working from a task list of priorities - handwritten at that....

I've also been hitting the snooze button on the calendar reminders quite frequently.

Anyone else struggling?  Any other tips?  Do I just need to come to terms with the fact that some balls will get dropped.  Everyone enjoys the juggler, right?
