Your gender should not dictate what you can do. Girls or boys can be teachers, fly airplanes, build bridges, bake delicious cakes and pastries, clean houses and make a good work of raising their kids. They both can be doctors and nurses. It is wonderful to find your dream and it is up to you to make it come true. It can be helpful to talk to someone if you are still having trouble making a decision.
Every decision is a risk and with practice, decision-making does get easier.
Explore your natural talents and learn what you do well, analyze what activities give you satisfaction and pleasure, and identify the kind of future lifestyle you want. You have to be awfully good in a sport to become a professional player. Hard work and practice are also necessary to succeed. In many places people have to travel a long way to go to school. Sometimes weather is very rough for many days and even months.
