How to become a commodities trader

[r3vbr]

To those of you who have experience on the field, what books do you recomend, how did you start?

I think it's a given that you should specialize in a few if not a single market like for instance soy bushels or something like that.
So therefore if someone is just starting out, wouldn't it be very important to measure how many people trade a given commodity and pick the one who has least professional traders active and specialize in it? (I don't have a clue about where to get this data)

Also volatility is a big plus for every trader, but is it mandatory for the goods to have an uptrade in prices or does the good commodities trader earn money in both bull and bear markets? In other words, do the prices have to follow an up or down trend for traders to make money or can you time the market on times where the prices are flat and vary only due to "noise"?
