playing in the gambling are fun and relaxation from the stress but don't put your mind to got profit in gamble your money is in the risk even the gambler have a lot of skills are you put in the hole your money thats the reason people become addicting.
To turn it to a profitable activity, continuous learning or honing of skills should be attained. You may want to have a master or a sensei to do it. Gambling games like poker or other card games is what I meant.
Skills indeed will increase your chance in making gambling profitable. However, when you say profitable activity its sounds that you will always win which is not the case even if you are already skilled. Its gambling because you gamble, you tAke chances and theres always a chance that you will lose.
