How to Stay Motivated When Things Change

I had a plan on being able to launch SMMA in April or May and we're now almost in July before it's going to open. So that's another reason why I had like a terrible month and I felt like my business was over. How do you stay motivated? A lot of my motivation is just out of need. There are other people who depend on me to be successful. And so I guess I think about them, but also the people who have trusted me with their businesses.
