How to blog?

Despite having mostly unmonitored access of the internet from a pretty young age I never figured out how to share? I always felt like my life was uninteresting and I had nothing to talk about, and then as the years went by more and more I just preferred to just watch others and retweet and reblog everything everyone else makes rather than making anything myself. It got to the point where I felt like it wasn’t my place to really be making post about anything at all, that I was only supposed to watch. I’ve decided I’m gonna stop letting stupid ideas like that hold be back from how to have fun, which also means that now I get to figure out how to blog like a decade late lmaoooooooo.
