The biggest personal obstacle I'd have to overcome would be dealing with people. In particular the employees and customers. Dealing with people all on a different place on the mentality spectrum is challenging to say the least.
If you start with a business partner and the roles are clearly divided and it's that person's strength, he/she could take that part upon him-/herself. Of course, that is in an ideal situation and it's not always a possibility 😅. !LOL
Besides, as an owner you should know all the ins- and outs of your company, so getting acquainted into that role is essential.
