When I started I ran into the "hmmm what to write today" issue often but with time and practice it really does become easier.
Everyone runs into this on Hive, unfortunately and it is normal. Handling it right is what divides us.
There are literally thousands of experiences we have on a daily basis to draw from and so many opportunities to think of posts with pictures as inspiration too.
I couldn't have said better. I just hope people can see that and change in time.
