Given the inheritance from his grandfather, Gary is abandoning his dream to become a medical doctor but instead will train to be a social media influencer. As a part of his training, he is looking to join a Mr Beasts training camp which will cost him $170,000 per year. The social media training will take two years to complete, and Gary will stay with many famous influencers during his training. Once he has completed his training, Gary is expected to be able to generate annual revenue of $75,000 from YouTube, $10,000 from Instagram and $50,000 from Tik Tok. Due to the short span of his social media career, Gary is expected to generate income for only ten years after graduating before he is no longer relevant. If the interest rate is 3.12 % per annum, is the social media training investment worth it? Explain with the figures.

Gary can go to medical school at Harvard University, which will take him seven years before he can generate any income. The medical school will cost him $80,000 per year and $30,000 on medical books and any costs associated with it. After graduating he can be a doctor for the next 30 years before retiring and generate $150,000 per year for the next ten years and $250,000 for the rest of his career.

Which career option would be better for Gary?
