My big thing in terms of advice is to just Start the business. Its not going to turn out the way you want it to, almost certainly. Whether that means you need to make a small pivot or the business was not meant to be there is something that is not going to work out the way that you are expecting it to. So I think the important part is to just start and you will learn as you go, adapt as you go, and pivot as you go. I think that is really the most effective way to learn.
