One thing we can all count on in life is that it doesn't last forever. Time marches on and before you know it our time is up. This is encouraging when it comes to the hard times. It's nice to know that grief and heartache won't consume us forever but when it comes to our dreams, this is a call to action. The things you are pursuing won't always be there. The people you love won't always be around. This shouldn't paralyze us with fear, but it should give us the push we need to be present in our lives. I guess the real question is, what are you waiting for?
