Indeed the worth of a man is in his value,the problem you can solve and how you go about solving it, money is in men pockets and the only way you can have access to it,is through their needs,solving their problems(needs), to me i think the fastest way of making money is finding what is lacking in your immediate surrounding solve it,and by doing that you are creating value for yourself which will in turn attract wealth,And the more valuable you are the more attracted you become.
