I had a very solid drive when I was 15 to ordain. I knew it so clear in my heart - Or so I thought. That was 5 years ago. I still feel I will ordain, but increasingly I feel that it may be 5 or even 10 years before I am really mature enough to make that commitment. I don't presume to know your personality but perhaps my own experience can provide you with some food for thought.
Things must take their natural course. If you're anything like I was you may even feel some frustration right now that you can't just be 20 and get it all sorted. It helps to remember if that's the case that robes and a bald head are just outer form. While they offer significance and meaning to those who wish to take that step, getting ordained doesn't make you a better yogi unto itself, the goal is simply to provide the most conducive environment for achieving progress in the Noble Eightfold Path. Those who wish to be monks and live the holy life for the right reasons are deserved of veneration and respect because of the difficulty of the life that they pursue. Living the life of a monk is very easy to romanticize from the comfort of the living room.
"For a disciple who has conviction in the Teacher's message & lives to penetrate it, what accords with the Dhamma is this:
'The Blessed One is the Teacher, I am a disciple. He is the one who knows, not I." -
