Sacrifice is not a topic which can be covered in a 700 word article, it spans way out past the horizon. To be an entrepreneur means sacrifice of all kinds in several parts of your life, yeah that part too. I would know, I’ve been living this for a while. You sacrifice spending time with friends and family, you lose sleep several nights a week, and you have to sacrifice junk food, because it will make you unhealthy at some point, not to mention lessens your already disturbed focus, and some will even sacrifice their health for that contract or deal you’ve spent months working on (guilty).
