Forex Tips : One Currency Pair Per time Per Trade

Focus one currency pair at one time while you are playing makes you become more efficient, which is "if you ever have one chance, which currency pair would you be playing, and how would you know is it at the right position?". 

In gambling, normally a person will focus on a particular table, if she/he decide whether today have the luck or not.  (what we normal people call it as 'luck') but actually they have their own strategy, such as

betting a limited money to ensure he/she stay in the game longer and a rule for himself/herself to feel whether today is enough is enough, meaning enough winning as well as enough of losing. In other words, today might not be a good mood. Strangely to say, a bad mood quite easy to lose.

Diversify your money (resources) into more than 2 pairs makes you tired, and you would not able to place your 'more money' per pips if you diversify too much.

In addition to that, you would find yourself closing all the currency pairs at the same time when the market does not follow you, and you do not have a targeted stop loss for all the currency pairs.

By the way, why do I compare gambling with forex?
Some of the games in gambling involves calculations. And of course they are similarity of the following

a) with greed
b) with fear of losing
c) with emotion breakdown
d) could not stop playing
e) 90% losses

Not forgetting there do have winners in the gambling as well. So how do they win? I don't believe they cheat but they do have skill on their own. But do they teach us? For those who are successful trader in forex, do you think they will teach us in the public then? Doesn't it would look similar?
