After reading replies from some threads on this gambling discussion board, I see that many people have already delivered suggestions related to various problems of gamblers. Now, it depends on us to follow or ignore the suggestions. Or we can take a look at the suggestions that are suitable for our problems. Here are below:

1. You shouldn't spend much money because it will harm the family. (Limit your funds)
2. You must have good self-control, it is one of the keys to be successful in gambling.
3. You mustn't get loans, you will be trapped in debt at the end.
4. After you can win in a gambling game, you are better to stop. Don't be greedy!
5. Don't expect much to win in gambling, most of them are luck-based. Think rationally!
6. Don't spend all your time gambling, have enough time for family, friends, and society.
7. Etc

What do you think, guys? Are all the suggestions worthed to follow by all gamblers? Let's discuss it, you can give any feedback or opinions.
Please let me know if there are other good suggestions! I will add them to OP if I think it is a nice one. I really hope this will be helpful for us.
