How do I choose, and where do I start the right path for my life? I am wavering between monasticism, marriage or celibacy?
Monasticism is not a 'career' to be discussed or analyzed for its pros and cons on the light of circumstances, be it family, age or any other circumstances. It is a call which if you do get, you will find that nothing else is more important and no one can hinder your decision. "He who loves father or mother more than Me is not worthy of Me. And he who loves son or daughter more than Me is not worthy of Me" (Mt 10:37,38). I am not implying here that everyone should leave his family and pursue the monastic life. As long as you are hesitating, know that it is not your path; at least for now. I advice you to pray and ask God to reveal His will for your life, a way you feel comfortable and not hesitant to take. Also a spiritual direction from your confessor father will be very helpful.
