Assume all guys here are gamblers. So, no people can have moral advantage than others. No Judge.
No matter what the reason is, you plan to gamble as a major income or only income source. This is super super hard. Sorry for you. But I have three personal opinions.
Opinion One, a few people called Professional Gambler take gambling as a job for a living. These people have the skills to make that happen. My scheme is working on that. But it looks like so scam to many dudes, so you judge it on your own risk.
Opinion Two, there is no sure win methods or 100% profit strategy in gambling. If someone claim that, I will just go away because I won't definitely buy that. You believe you pay. I don't believe, just leave. Keep life simple. No judge to the buyer or seller. We are not the World Cop like Uncle Sam.
Opinion Three, this is the most important one. YOU. No one put a gun on your head to push you to gamble. You can do anything if you can control yourself by supreme rules. Like the stop-loss, stop-win, gamble hours per day......The key is self-control. Comparing the power of self-control, others are unimportant. Some people success, then they can be called professional gambler.
After gambling soooo many years, sky city Auckland, the star Sydney, crown Melbourne, nationalcasino.com, stake.com platinum5 (sylviegreta), wolfbet.com......still struggle hard to become a professional gambler......This is the inmost thing on yourself......Others are the camouflage of the essence of gambling. If these opinions make you find the right direction, I will be super happy.
I agree with the OP assumption when he said all guys here are gamblers, because life itself is a gamble and chances of survival varies, apart from using casinos and online gambling sites, we make wrong choices daily knowing the consequences but still decide to take chances, that's a form of gambling, I've read replies and discovered a good number of people made statements concerning taking gambling as a form of entertainment instead of going professional, which I think is the best way to go about it, when people refuse to yield to strategies or try to avoid gambling it's not being judgemental, it's called risk management, because in as much as it's been beneficial to some people, it's ruined lots of lives and families, and OP it's a good thing you stated that the professionals in gambling are few therefore it should be informative to people that not everyone would be very successful in it asides professionalism their are people gifted with luck, they make less effort in life and come out successful even if it's on the first trial but these set of people ain't much.
Therefore it's advisable to understand that all fingers are not equal and what works for Mr A might not work for B, discovere what you do best and stick to it, if casinos and online sports betting doesn't work for you then you should quit and focus on other means of earning a living of which gambling is not only an option for that, not everyone would make it through gambling if not the world would had been filled with more rich and less poor people.
I put it to you that even most professionals gamblers suffers great loss at some point, to be being professional doesn't only mean being highly skilled or how often you've been successful, the most successful and wise gamblers apply what we called risk management in gambling, that is to avoid greed and knowing when to quit for the day.however beware of people that claim to be professionals and would ask you to pay certain fees for sure gambling tips and odds because there's no 100% guaranteed tips or success in gambling and no one is going to refund your loss, just like the OP stated, beware of scammers.
