You are preparing now to fulfill a unique mission on the earth. Read Doctrine and Covenants 88:119. In your journal make a list of your hopes and dreams for your future home, family, and education and some important things you would like to accomplish in your life, including becoming a wife and mother. Then write a plan that will help you achieve your goals. Share this plan with a family member, leader, or friend.

Planning is key to preparation, but after outlining your plan, start doing what you can NOW to accomplish your plan.
You don’t need to limit yourself while considering a career by narrowing your choices down, but seriously think about what you could do well, and educate yourself on the qualifications necessary by meeting with somebody with the occupation you have in mind.
