Answer:
This is a weird question, but I'll try my best to answer.
Step-by-step explanation:
Your interest in Mars could lead to wanting to learn more about the planet. Perhaps that fascination could turn into an interest for other planets, then space in general. By wanting to learn more about it, you'll probably want to study it, maybe even go to school to continue expanding your knowledge, then that could lead to a job a career in astrology. Perhaps someone could even just grow an interest for the rocks of Mars and go on to study different rocks and minerals. But I'm not sure. This is the best thing I could think to explain it.
