One realization is just how blessed I am to have so many people who love me and whom I love. I HATE saying goodbyes, but sometimes goodbyes cause me to value my loved ones even more than I usually do.
These years could have been a lot easier. But, except for the times when my selfish decisions got in the way, they could not have been more blessed.
Perhaps this is the secret behind Jesus' words, "It is more blessed to give than to receive." (Acts 20:35)
