I would prefer seeing fewer aspirational posts/tweets/etc. I'm not terribly interested that you've started to read a book, but please do let me know how you liked it when you're finished. It's great that you're planning to work out every day, but why tell me that? Intending to regularly write morning pages before breakfast isn't actually writing anything, but I can't wait to hear how it's helped you after you've done it for six months.
Writing aspirational posts can be self-motivating, and I'm guilty of it myself. And of course feel free to write about anything you damn well please. I'm just asking for fewer before and more after posts.
