Perspective... New perspective: for me, for you, for life. Perspective is everything because it's intimately tied to learning. I've seen that when I'm struggling with something, it's because I need new perspective.
Communication... I've realized how important it is to talk to each other, learn from each other, and be open minded with each other. Whatever the problem, you need more honest communication.
Love... Yep. For some, the older we get the harder it is to love. But LOVE, as corny as it sounds, is the biggest and most important thing in LIFE.
(I think no two people will ever be loved by me the same.)
