How do you start your own business? (If you don’t know how!)

I am not a natural entrepreneur. I come from a long line of civil servants and teachers. Not the stock of people who would start their own businesses. I can only think of two people in my extended family who have their own businesses. (both are dead) All this is to say? How do you even it?
I think to have that mindset you’ve got a leg up if it’s something that people in your family do. My family was all about getting a degree and getting a profession – teacher, lawyer, doctor, engineer that was our goal. (And I don’t think we even knew what that meant, just that is what you were supposed to do.)
To this day my Mamá, doesn’t know what I do and will question why I don’t go back to school for some ephemeral magical degree that will allow me to be a “professional” Not sure that means.
Anyway, I’ve been thinking of taking the plunge into business, but I don’t know what I would do or what the business would be? Technology? Agency? Lawn mower? Still unclear… The internet has all the information you could ever want on the subject, but thats all there to stop you. What you have to do… is just DO. One step at time. One hurdle at a time. Move forward and start delivering value at a price. Easier said than done.
