i know that when i first started working for myself it made me happy and the money came second i also found i had to chase the money from some off my clients that made me unhappy it soon dawned on me that if i spend less ,worked harder and longer i could create a buffer in time. not needing to be payed so soon i could also be more selective who i worked for the late payers got the flick.. that made me happy those who did not appreciate what i did got the flick .. that made me even happier in all my years off working only 2 scum-bags did not pay the full amount but i accepted that to be their failure so i stayed happy achieving something can make you happy and sometime people pay you money for it so i think just having money is not the answer but if you make money doing something that make`s you happy bloody great
