Then, we stop believing in Santa Claus. As we become older, we gain a perfect view about who was our Santa Claus all the time and that the concept of Santa Claus is ridiculous. It's not and easy phase, with puberty hitting in with a lot of complexes. But there are also good times, in this age, we achieve many goals and dreams, and having adventures with your friends.
When we realize, we are Santa Claus, we are parents. We are our children Santa Claus and it is our mission to keep their dreams alive, ignoring the fact that the "real" Santa Claus doesn't exists. At this time, we don't have many significant or drastically life-changing goals, just keeping our current life styles and maybe improving it but not in a radical way.
Finally, after being Santa Claus, we start looking like him. Getting old, the physical aspect isn't important anymore, we get fat, bold and facially hairy. The cycles continues.
