Wealthy is built by every other goal we have set to gain wealth it is not something that take turns. If you are not building wealthy gradually the don't think you will get wealthy because time will be all over and there will be nothing to show for.
wealth is created via investment that returns profits on investment and has a great potential of growth over a given period of time
