Sometimes it's not about focus but motivation. A need to know that the hard work, or just the work you put in to something is going to show some type of rewarding results. Especially, when you are trying to work through adversity, and things just don't seem to be going the way you would like. It's not easy. Will it make you stronger? What is the saying, "If it doesn't kill you it will make you stronger."
You're motivated to get up to go to a nine to five everyday to get that weekly paycheck. But, what's the motivation to get up and get going everyday when you work for yourself and there may or may not be a weekly paycheck. People tell you, "Oh, I could never do that. I admire you for that because I need to know at the end of the day I have a paycheck coming in." Is is admirable or stupidity? Or is it stepping out on faith?
