Hey there. I've been on Steemit for about 6 weeks and the first few weeks I spent a lot of time wondering what to blog about as well. Finally, I just loosened up and started writing about stuff that I was naturally thinking about and it got easier. I've even started writing about my dreams because I wanted to have somewhere to put them and found it was easier to do it here than write it out long hand in a notebook. I think you'll find that stuff will just start seeming obvious to you. Also, I think it's good to try not to get too niche, just keep it a bit fluid. That has worked for me and the past couple of weeks have been a breeze. Good luck!
hey thanks for the advice @tacostate. Much appreciated!
