I also struggled with keeping up to appointments, plans and promises, especially ones made to myself. I hate to disappoint people but don't mind disappointing myself especially when it wouldn't hurt or when it gives me some kind of leisure to gratify my immediate desires. But this I've realised is what what my major problem is.
I can't say if it's entirely just procrastinating or just complacency.. I've always needed to remind myself to be present in the present. And talking about relapse, you're not the only one.
I found that about myself because during my school days, I would make sure to pay good attention during lectures, I don't take notes and I only start preparing for exams just few days to the start of the examination. And giving the complexity of this exams, one would say it's a sure way to fail an exam. Funny cos I will not only pass but as one of the best.
Lately I've realised how bad such an approach to live is. Doing things only when it's convenient for your or when it's die minute. When something has already gone wrong or is about to go wrong. Things you could have done better and with more ease if you did them the right time..
And so I keep reminding myself everyday as well to be fully present in the present.
I took notes that I couldn't understand come study time, and struggled. I am not smart enough to pass easily! :D
Perhaps with all these smart devices and their notifications, rather than sending us reminders to pay attention to crap, they should remind us to be present and not on the screens :)
