Having a hard time allowing myself to explore my business

I’m starting a new business and I want to give myself permission to explore it. However, when I think to myself “I choose to allow myself to explore this,” I feel uncomfortable and resistant. Thoughts like I can’t do that, I should take it more seriously, that’s not taking it seriously, and I should be more committed come up and I have a hard time getting past them. Any help to shift this so I can get out there in my business would be greatly appreciated.
