As I've gotten older, I've become increasingly cognizant that most of the things that I valued more in my youth don't seem so important anymore. Pretty much most of the main things that society has conditioned us to value, e.g., money, cars, power, big homes, etc., really aren't the things that we can depend on as constants, and are therefore not that important in the long run.
What ALWAYS will be constant is PEOPLE, and your relationships to them.
Family and friends- people that you care about and that care about you- will never go away <until of course one of you expires LOL>, and your RELATIONSHIPS in this life to the people whom you value are all that really matters. We aren't here for that long when you think about it, and I've come to really value interacting with family and friends. Everything else can go away, but your family and friends will always be constants in your life. Spend time with them, and LISTEN to them. We all get so caught-up in our own agendas at times that we don't stop thinking about ourselves and REALLY LISTEN to someone else. Whether they are sharing a story, talking about something mundane, or whatever- when you consciously make an effort to LISTEN to what others have to say, you become cognizant of how unique everyone is, and how lucky you are to have crossed paths with them.
