I have spent the past seven months planning a retreat in Mexico this upcoming December. I already signed contracts agreeing to the dates of the retreat and to be there for the event. Lots of people paid their dues, expecting to see me in person. This is all binding, and if I renege on my agreement, I lose an opportunity to make a lot of money and disappoint a lot of people and damage my reputation and that of my business. My brother got engaged recently and he and his fiance went and planned the wedding on one of the days of the retreat, unaware I had this scheduled. They tell me they cannot change the date of the wedding. My parents and my brother want me to forget about the retreat and come to the wedding to see my only brother get married. What should I prioritize, the wedding that my parents and brother want me to be at, or the retreat, which is important for my business?
