Negative thoughts about physical product business

I am starting a business where I’ll be coming up with a physical product to sell and hire a manufacturer to produce it.

I am having a lot of negative thoughts and feelings about it:

– I don’t know enough to do this.
– Who am I to start this business?
– It’s only “right” to start businesses that one is passionate about before starting.
– I’m not passionate about any specific product, so I shouldn’t be starting this business.
– It’s wrong of you to start a business where the main purpose is to make money.
– I’m concerned I’ll be adding to the world’s suffering by buying from a manufacturer.
– What if the employees are mistreated?

I would love some help untangling these thoughts since they feel like reality to me and not just thoughts.
