New business/overworking

I started a new business in January and I am noticing that I think about it all the time, but when it comes to actually doing anything in it I get stuck.

I always think thoughts like:
This doesn’t seem fun like I want it to.
I have no idea what to post about.
I’m getting nowhere.

I’m aware that these are thoughts, but I haven’t found thoughts that make me productive in my business to do the money-making things.

The second thing is that I get burned out of it easily because I think about it a lot, but don’t actually do anything about it and it burns me out.

I don’t want to stress about it, but I am stressing because I’m not being productive in it.

How can I change this?
