When the author was working in Wharton she felt overwhelmed and said, "it suddenly seemed that quitting everything and moving to a sunny, slow-paced island somewhere was the optimal solution. I’d invite Leo and Rob to join me. Before I asked Rob to walk away from his career and pack for the beach, I needed to know whether I’d indeed be happier trading an overflowing to-do list for a blank one. With more available hours in the day, would I actually feel more satisfied with my life." She then realized she could make small changes to be happy, ". By protecting work hours from waste and distraction so that I could produce more of what felt purposeful during those hours, by prioritizing time for activities that filled me rather than just my schedule, by outsourcing some chores so that I could instead spend that time playing with Leo, by savoring and celebrating day-to-day moments as I shared them with the people I loved . . . maybe I could “do it all.” Rob could reserve packing for our next vacation." For brighter days, I did eventually ask Rob to move, and it happened to be a place with a beach nearby. But, except when on vacation, we don’t spend entire days relaxing. We are now raising Leo and our daughter, Lita, back home in California. I don't understand what does "Rob could reserve packing for our next vacation." mean? what does "reserve" mean?
