Dear Brendan,

There is nothing to stop you in your heart and soul from offering your life to Christ and allowing him to do whatever he wants with it. If you really think that your call is to religious life you can also promise to him to do those things that are going to help you grow in your vocation, and avoid those that will not. If there is anything in what you call a regular teenage life that you see will not help your vocation, you can freely give it up in order to protect and make your vocation grow stronger.

Make sure you take care of your health, your mind, and your soul. Stay active, be a good student, and grow in the life of grace. Maintain good friendships that are constructive, and do something for Christ and others every day - be his apostle right now. 

If you want to, let me know where youre from and I may be able to put you in contact with other kids your age that are trying to do positive things for Christ (they have projects, clubs, do missions and outreach to other teens, etc...).

God bless,
