What makes a good investor?.. first you've got to have a brave and tough heart because its not easy to invest without consideration if we will gain or not we have to accept that in every investment there is always up and down situation before you really hit the target and succeed. and that how we felt every time we sell and we lose..secondly you have to invest only on what you can afford to lose to avoid frustration, do not put your money into one investment alone.. you need to have a variety.
