never blogged before

I am learning there is a lot more to selling my goods than the production side. all the website work, advertising, and now blogging.
so here I am, my first ever blog. can you remember your first ever blog? what was your subject? was you as nervous as I am right now? dont even know if I am doing this right! so if there is anyone out there who can let me know what to do to make this work, please message me, or blog or something lol.
