I only visualize the futures where future!Me looks back at his old posts and cringes.

You say you anticipate cringing... is that a correct anticipation? Do you currently find yourself frequently beating yourself up for things you've said or written? If so, maybe that's the bug you want to fix first. Reinterpretation can be a good strategy; maybe try to frame your past post differently. For example, despite whatever factors you might find make a post of yours cringeworthy, it seems likely that at least one person found it valuable, interesting, or at least amusing.

Anyway, welcome!
