Focus and discipline.
So many people over think success. Your mind wants you to think that there's a little shiny trick in the book that you are missing out on. However, most honest entrepreneurs who made it to success will say it's simple.
It's all about focus and discipline on the little things. I will leave you with these two great quotes:
"The man who moves mountains, begins by moving small stones" - Confucius
“A woodpecker can tap twenty times on a thousand trees and get nowhere, but stay busy. Or he can tap twenty-thousand times on one tree and get dinner.” — Seth Godin
