Based on my experience, because we are owning a small bake shop, first thing we considered is the money we need or the capital itself. Knowing your capacity financially is very critical, it includes the money you need for your stall, product, and for the people you are going to hire for example. Next is ofcourse the location or area you will be choosing for your business. It is very crucial nowadays because places that are good for businesses are mostly populated, but putting your business in that kind of area is  very good for your concern which is business. Another thing is about "backup budget" or "extra budget" just in case your business didn't success, but don't worry about it businesses always go through struggles it just a matter of trial and error. Goodluck to you and to your business! 😊😊
