What are some realistic ways to earn 10 cr in 20 years?

 Earning 10 cr in 20 years is a significant goal, and it will likely require a combination of consistent effort and smart investing. Some potential ways to achieve this goal include:

Investing in the stock market, using the principle of compound interest to grow your money over time. For example, if you invest 10 cr and earn an average return of 10% per year, your money will double in about seven years.

Starting a small business or side hustle, and using the profits to invest in growth and expansion. For example, you could start a lawn care business with just a few hundred cr, and use the profits to invest in more equipment and hire additional workers.

Participating in a savings or investment plan that offers matching funds from your employer. For example, if you contribute 10 cr per year to a 401(k) plan and your employer matches your contributions dollar for dollar, your money will grow even faster.

It's important to note that these strategies will not guarantee success, and there are no guarantees when it comes to investing. It's always a good idea to do your research and consult with a financial advisor before making any major financial decisions.
