I would never pursue a career of successful gambler because I'm trying to eliminate uncertainty, as much as possible, from my life, and there is a lot of uncertainty in gambling. If you have wife and kids, you are no longer risking by yourself alone, but you are putting all of them at risk. A family man just can't rely on something with so much chaos in it as gambling.
That's pretty safe, but if you have the skills, aren't you gonna invest on it?
well, I get your point, not every gambler are willing to take that journey due to its risk level and even if we really tried our best, there's no guarantee that we will be successful in the end. I don't know, maybe it's just me, until now, I am still looking for ways to improve my skills and to be consistent as it has been a dream of mine to make big money in gambling, which until now I can't still find a clear path to walk.
Gamble according to online dictionary:
1. play games of chance for money; bet.
2. take risky action in the hope of a desired result.
The first one do not properly define gamble. I prefer the second one.
People do not realize how often they gamble in life. We take risk always for desired result. But we have to work harder and be well prepared to lessen the risk.
I believe the most skillfull/knowledgeable ones could earn a living from what the less-skillful or less knowledgeable termed gambling or random.
I prefer safe games though.
Better to gamble on things that earn you a living, in my opinion. Example, you own a successful farm and occasionally gamble on weather/rainfall or bet on competitive online farming(stimulated farming) games
