Parental Flaw

I've come to the realization that among my many flaws as a parent, one of the major ones is that I seem to lack the ability to think things through. For example, when we got the 7-year-old an advent calendar that contains 25 individual Star Wars-themed mini-Lego sets in it, I thought it'd be a fun little thing for him to do every day, being that he's big into both Legos and Star Wars. What I didn't realize was that what I was actually buying was a new, blond-haired alarm clock that would be entering my room every single morning somewhere between the ungodly hours of 5:00-6:00 AM while I'm still peacefully slumbering, that would immediately turn on the light upon entering, and then (and the order here is important) ask if he could turn on said light (and not wait for my response) and then ask — nay, demand — that I help him build, essentially, a tiny, 20-piece puzzle when my brain is barely functioning enough to even comprehend where I am. This flaw is something I need to work on, I know, though it's been 12 years now since I first became a parent so I admittedly don't have high hopes of any improvement in this area.
