About this module

Investing is not gambling, and it is not just for rich people. It is the mechanism by which ordinary people build extraordinary wealth over time. This module covers compound growth, why index funds beat most active managers, and how to start even with $50 a month.

Key takeaways
  • $100 invested at 8% becomes over $1,000 in 30 years - you do not need a large starting amount.
  • Index funds track the whole market and outperform 80–90% of actively managed funds over 10+ years.
  • Risk and return are inseparable: higher potential returns always come with higher potential loss.
  • Time in the market beats timing the market - starting early matters more than starting perfectly.
