As we get older, as a parent, we don't have time to define ourselves, as we are struggling to juggle all the never ending responsibilities, trying to live through the day.
So, the best time of our lives to define ourselves, are actually during our prime years.
And yet, those are the highlights of our life, as we are having the taste of freedom and ended up busy fascinating about this brand new world instead.
Life is indeed short, and you will only say that after time passes you by.
Define yourself, define your time, and you will find that time is actually waiting for you, waiting for the moment you realise who you really are.
