Quote from gnome:
By some of the definitions of gambling here ("Anything that's not a 'sure thing' is a gamble"), then driving to the office WOULD be gambling.
To understand the true meaning of gambling, one needs to look no further than Vegas. The patrons "gamble" because they are hoping to prevail against odds which are against them.... and there's nothing they can do bo put the odds in their favor. To the house it's not gambling but a "business"... because the odds favor them. Large numbers of chances (bets) means they are guaranteed to win in the long run.
For traders who perceive the market as gambling, the best thing they could possibly do is stop trading... immediately... because in the long run the odds are 9999/10000 that they will go bust.
Just a comment...if we carry your equation over to all business ventures, then no one should ever go into any business...as we all know, 90+% of all business ventures fail....and, one step further, 85% of all employees are fired at some point in time (not as applicable, but relevent).
At least in trading (with us anyway), you don't have to buy a franchise, lease a building, start a restaurant, etc........and you have a very limited risk with an unlimited upside...just a point to keep in mind.
All the best,
Don
