From ...
To my humble understanding: We can't be too greedy in the market, if you want to grab all the money in the market (long and short at same time), the result is you lost all your money at the end.
If you believe you are smart than the most people, then long or short once a time.
I know I am not smart enough, so I do long only, will never ever do short again.
