I think the difference is a growing awareness of the limitations of my life and potential, coupled with a growing appreciation of the boundless things I could do to learn, enjoy myself, and improve my life and others'. I think when I was younger I just saw something fun and exciting and went for it. As the years have gone by, the sheer number of things that I have identified as fun as exciting has become so overwhelming that "fun and exciting" seems utterly unhelpful for narrowing down the possibilities. I can also look back now and see how many things that I was sure I would do in my life haven't happened yet. Plus, like another commenter pointed out, life obligations keep mounting up.
