There are various investment targets, there are those who succeeded and those who failed. Unfortunately there are no successful investments for every investment object. I think that those who succeed in investing do not know the solution. However, their success,it was simply luck.
That is how reality hurt as sometimes, not all your plans suits on what you expected to happen but you have to be open minded in that possibilities.Investing is a risk that you must face on, there are beautiful outcome or good profit and the end but there are also big chances of losing money and be ready for it. You must know personally of what you are investing for and if you are open minded to accept the possibilities of failures.
