I was wondering if anyone has ever had the feeling, like I get sometimes, that they were addicted to 'meta-level' optimizing rather than low-level acting? As in, I'd rather think about how to encourage myself to brush my teeth more than brush my teeth.

This is fine if you then go and implement your meta solution. It may not be the most efficient solution but if meta is easier for you and you can follow through on it then harness it. (Works for me!)
