33 is a birthday that many people celebrate with cake and presents. Whether you are celebrating on April 1st or any other date in the year, there are plenty of reasons to celebrate this special day. One reason to mark 33 with joy is because it means that your time has come. As we get older, we learn more about our own mortality and the shortness of life. We also face greater challenges every day as we try to figure out how to live a happy and fulfilling life.
