I think One of the reason why people remain poor even while earning a decent amount of money from their businesses is the fact that they see money as a spending means and not investing....
Money is expected to be used for an investment, once we have invested and done doing this, then we go later after using little part of it we earn to enjoy ourself and also do other things we ought to have done, we should not spend from our investment fund, instead, when we make profits, we should only spend little part of it and use the remaining to reinvest, because we are saving ourself form any further future challenge when we are investing then spending it.
