It was being said that once you don't clearly understand what you are doing, you'll just end up nothing.
Investing comes with a certain preparation;
 - money as for capital ( borrowed or personal money)
 - knowledge and skill ( includes strategies)
 - time
 - gameplan

A failure to acquire these things will never succeed. I haven't found a perfect way to do trading but what I've mentioned above will certainly help to avoid big losses.
