Lol I deliberately said a [I]good [/I]plumber!
I was being a little glib, but to my mind it is too easy to compare gambling and trading, because there are some obvious necessary traits-in-common such as patience.
If I gamble, I sit down in a group and we compete, and take money, or at least the potential for money, away from one another. I think that trading and gambling have various things in common, but then so do umpteen other professions, however they also have many key differences.
And imho a good trader is paid for their time and expenses, regardless. A trader who is not is either still on the learning curve or is in the wrong business. Sorry to any noobs reading to whom that might sound harsh!
