<prompt> Human: What kind of yearly income would I have to start at now, work towards in the future assuming that I followed all the general rules of PF, to achieve 20 million dollars in investments, cash, and assets with value? I know that this kind of question is dependent on a lot of different factors. Lets assume I live in a city like Seattle, I saveinvest at the recommended levels, and I live a modestmiddle class life style, I only use credit for a house. Lets assume that any money I dont use for livingsavings fund I use to invest in aggressive growth opportunities for the next 15 years, and the remaining years I put that money into a moderately aggressive to conservative portfolio. This is more or less an algebra question where we are trying to determine the variables in order to achieve a specific value of x.EDIT: I forgot to put in the time horizon. Currently 21. Starting at 0. Goal is 20 Mill by age 40. vs. 50  <response>: Youre gonna need more lentils
