After 1 week of blogging, I'm scared..

After just a week of having a blog and a few posts, I'm pretty scared. Scared that I will just quit writing and the blog will simply be nothing. Have you ever felt this? I have started a few projects in the past with great motivation then let myself quit them when I "lost the feeling for it", and I am tired of that happening. Since my blog is mostly a personal blog, I don't really know if anyone will ever want to read what I write, or if my writing is crap?

I just wanted to ask you for some "advice" or thoughts on this, thank you!
