The chances that your children will delay sex, pregnancy, and parenthood are significantly increased if their futures appears bright. This means helping them set meaningful goals for the future, talking to them about what it takes to make future plans come true, and helping them reach their goals. Tell them, for example, that if they want to be a teacher, they will need to stay in school in order to earn various degrees and pass certain exams. It also means teaching them to use free time in a constructive way, such as setting aside certain times to complete homework assignments. Explain how becoming pregnant - or causing pregnancy - can derail the best of plans; for example, child care expenses can make it almost impossible to afford college. Community service, in particular, not only teaches job skills, but can also put teens in touch with a wide variety of committed and caring adults.
