<prompt> Human: I have a goal of making 100,000 by the end of college college is paid for by parents, and use it for solely investing reasons. So I am aware of the rule of 72. Id like to have an 8 percent intrest rate to double my money every 9 years.How feasible is that? Ideally Id like to invest in mutual funds, and since Id be so young, high risk ones.Thank you!  <response>: If you are investing with a specific rate of return in mind youve already lost. You dont get to pick your investment returns.
