As a teenager, you pretty much have a mind of your own, of what and how you'd like things to be.
You may find yourself brushing up against your parents more often than before. Remember, though, to honor your parents - it matters as much how you say it as what it is you say. And the more responsible you prove yourself, the more trust and freedom you will earn from your parents.
Peer pressure will hit you hard. Plugging into a trusted community like your church youth group and keeping the lines of communication open with your parents will protect you from doing things you might later regret.
Dating is not wrong, but do yourself a favour - go out in groups. You'll have more fun and freedom to be yourself while you learn about the opposite sex.
