Don't get too serious about earning money in gambling. The risk is higher than investing just playing as usual while entertaining yourself.
I agree with this. We should consider gambling as a fun part of our life, and we can come back to play many times if we want. As long as we know how to treat gambling and we don't think that in the gambling, we cannot do hard work like what we did in real life, we can enjoy to playing gambling. The hard work in gambling will not count if you only want to enjoy the game because you will see that if you work in real life, that is the real hard work for you.
Doing hard work in gambling means, we use most of our time just for gambling stuffs and things, which isn't good for our financial situations. Yes, instead of making gambling as our main source of income, it would be better to treat it as a fun thing only, which we can achieve by doing it with just the spare money.
