Can we be real? What do you do on the days/weeks you just want to quit?

Occasionally, I will have days or weeks I just want to give up. I'm 9 years in. I have had a lot of ups and downs. I have learned hard lessons. I have experienced big wins and losses. And every once in a while I feel defeated. I try everything to grow and make my business better and then I find myself taking steps backwards and feeling exhausted over the thoughts of having to build something again. This could be team members leaving that I invested in, money I saved that I now have to spend on repairs, or unexpected losses, and the list goes on. We all have those days we feel like we just don't have what it takes to actually make it. What do you do? How do you keep moving forward? 

Share some hopeful stories. Share the worst stories and how you overcame. I don't want to hear how you just win all the time. Tell me the stuff that made you sleepless, the stuff that made you cry, and that stuff that you thought you just couldn't rise from. 

I need some encouragement that even when I think the worst is happening I can still overcome and keep moving forward and win!
