Noooo don't start!! It's highly addictive! Consult your doctor first
Joking, welcome to the party!
If you can be more specific I'm glad to help. What's currently blocking you? The "actual start" like choosing domain name, hosting, theme, logo? The "creativity" aspect? Like "what to write about"? The "analysis" side? Like "how many resources should I spend on this?", "what to expect?".
I'd recommend to start writing a "mission statement" and 10 posts idea. Then, while you hunt for a name, logo and all the technical stuff, write posts on textfiles for fun.
