I recently had a dear friend pass away suddenly--too soon, too young. It really made me think, "What would I do with my day if I only had that one day left." I certainly would not spend it stressing about my work and allowing my stress to affect my interactions with my family. I would focus on being present with those I love. Those were just the first couple of things that I thought of.
I think it's healthy and potentially life changing to stop every now and then and remind ourselves of what our real priorities are. It's so easy to get caught up in the day to day, the hustle and bustle, the frustrations, the tiredness and the feeling that we all sometimes get that life is hard. We would do well to count our blessings and do those things that we would do if we only had one day left on this earth.
