Some actual good, honest feedback here.
I guess it depends on what you call profitable. For example, making any profit or making $XXX,XXX+ of profit...
Anywho, there is a definite correlation between the time spent at this and the likelihood of being profitable. The thing is, many will just not be around long enough to get there.
It's similar to many other top paying professions. I was a stockbroker previously and we knew that when new brokers came into the office that those that did the work AND were 'too dumb' to quit had a very high chance of making it. We seriously would tell people that you had to be too dumb to quit b/c anyone with common sense would quit the job after about 1 week.
Same can be said of trading... how many around you will comment on how hard/stupid it is what you are doing but then/if you make it, more than happy to give you their life savings to trade....
Such is life.
