Keep a private blog, and consider posting to a public one those essays that you're particularly proud of.
See 3), I have an ugh field around looking at my writing that means if I waited until I felt proud of something I wrote I would never publish anything. My current workaround, which I've used for academic coursework, involves pre-committing to aiming for a minimum level of quality rather than trying to be happy with my work. After sufficient time has passed since writing, I can usually look at it more objectively. Which suggests that I should commit to posting privately and then revisiting posts a week or two later after the ugh field has faded
An exercise:
Name something that you do not do but should/wish you did/are told you ought, or that you do less than is normally recommended. (For instance, "exercise" or "eat vegetables".)
Make an exhaustive list of your sufficient conditions for avoiding this thing. (If you suspect that your list may be non-exhaustive, mention that in your comment.)
Precommit that: If someone comes up with a way to do the thing which doesn't have any of your listed problems, you will at least try it. It counts if you come up with this response yourself upon making your list.
(Based on: Is That Your True Rejection?)
Edit to add: Kindly stick to the spirit of the exercise; if you have no advice in line with the exercise, this is not the place to offer it. Do not drift into confrontational or abusive demands that people adjust their restrictions to suit your cached suggestion, and do not offer unsolicited other-optimizing.
