It depends on what I'm writing, like this visit is easy as I had a lot to talk about and it was just a couple of days ago, everything is still fresh.
I started a draft last year about my trip to Petra in Jordan 7 years ago. It's an amazing trip, one of my favourite, and apart from one unique interesting incident there isn't much to talk about to not make it too informative. Many people have written about Petra, even on Hive, so I don't want to just write another 'tourist board promotion' type post.
The worse thing about a travel post is just write " This is the entrance, i went in and turned left. This is a 100 year old building, its built of stones and has four windows in the front and two doors on the side. There is a clock at the top". Personally I find that a bit bland, and prefer to read about a person's experience at the place, but not necessarily a person's experience with their friends when they're at the place. Slight difference there.
Apologies I'm ranting a bit here. But to go back to your question, I think the best thing is not to force yourself to write. Sometimes I only post once a week, and sometimes I post random things. Maybe go through the communities for inspiration, perhaps you never thought of writing about your pet, book review, coffee, nostalgic toys, how you destress yourself, stuff you grow in your garden... Hopefully you'll find something that works. Good luck!!
