Building a business is like running a marathon out of shape, getting fit on the fly with no finish line in sight. You abandon your old life and can't go back, so you keep moving forward even though all the sacrifice might be for nothing.
Business is like starting to run a marathon when you're out of shape and then having to get in shape while you're running the marathon without resting or knowing how far away the finish line is, or if there's even a finish line at all. Business is hard every step of the way, and I think the hardest part of all of it is the uncertainty that all of your sacrifice will be for nothing, that we give up everything now for nothing later. You have to remember the life that you walked away from to pursue your dream, and you realize there's no going back to that, and so you just keep going.
