"No employer today is independent of those about him. He cannot succeed alone, no matter how great his ability or capital. Business today is more than ever a question of cooperation."
Orison Swett Marden, late 19th/early 20th century American author.
My career has largely been starting, running, sometimes succeeding, sometimes failing, in my own companies.
In all those times, the outcome was the result of what I did, what my partners did, and what our employees did.
You may think it won't be that way for you, and if so, that is your first mistake of many yet to come.
