My (diagnosed) OCD compels me to use leading commas. I also use "WHERE 1=1" so each where constraint begins with AND/OR. I tend to write a lot of "investigatory" SQL that requires frequent commenting. I rarely need to comment out the first column or constraint, so commenting in general is much cleaner & faster.

I did not learn SQL this way. I was shown these tricks and their adoption was near immediate BECAUSE it just made more sense to my brain.

This isn't to devalue/argue against your comment. I just find it interesting that the common denominator for OCD-ish compulsions is that the "right" way for an individual OCD brain is usually specific to that individual brain.
