It's easy to look back and think of the “good ol' days” even if those old days were last year. It's easy to look back with fondness, and it's great to have wonderful memories of the past.
However, it's so important to really be in love with where you are heading in life. Moving forward and growing are two things that never change in life no matter how hard we try to keep things the same. So we all might as well go with it.
