From the first two lines I was going to ask what your dental had to do with writing XD

From my experience and observation it's easiest to post stream of consciousness/something on your mind type stuff daily as all that requires is for you to start and then actually press post (some people like to polish it up, others will just go through looking for spelling errors, both of these are good things but can also lead to second guessing yourself annd declining to post which is what you don't necessarily want). So looks like you're off to a decent start XD

Otherwise just aim for consistency. Every few days or once a week is just as fine. Pop it on your calendar and don't let anything override it unless you personally consider it important enough. And don't sweat it if you drop a day, just try again next time :)
