Being a Pastor is not for everyone. It is a demanding schedule (you don't just work on Sundays!) and you need to be prepared to essentially be "on call" 24/7. If you feel called to pursue the ministry I strongly recommend you get the best possible Seminary education, certainly one that demands you know Hebrew and Greek (Latin and German are important as well) so that you can be as well prepared as possible. The ministry is not just another job, nor is it a simple civil function; when you are the pastor of a congregation you are responsible for souls and you need to be prepared to handle that responsibility. That all said, to be a Pastor is to have the most rewarding career the earth has to offer, so if you can handle it I highly recommend it.
I studied to become ordained clergy. I attended college for four years and seminary for three as a requirement for this "vocation". I have no regrets about the educational piece; I learned a great deal about the Bible, people and ministry. I am distressed however about women in ministry. They usually only last ten years on average. The Church is a cruel place for them. Someone really beat it into people's heads that women in ministry is unacceptable. Shame.
Otherwise the love of people, to be in a profession where you are making an impact is worthwhile anytime.
