Its entertaining to gamble and more fun if you win but losing is also inevitable and thats the reason why some of us are having depression due to the losses that we cant afford to lose and worse it became a door for other illness. I also experience to become addicted before and its very hard especially if you dont have someone to talk to about your problem.
Depression do not come from loss, it comes from the fact that people bet with the money they can not afford to lose. If you are able to lose the money you bet with, no depression will come.
Thats why its a must to set limit and have discipline. Its fine to gamble as long as you can control yourself otherwise better not to try.
One of the best limit to set is to divide your monthly income into 100, like having $2000 months income, using only and not more than $20 or less monthly to gamble is not bad at all.
Those are lucky people who have good sense of understanding what changes they are experiencing in their body. This gives an idea what to do and what not.
Keep a strong control over oneself is very important both in life and in profession.
My friend said he feels very strong change in body when he is about to face a loss. Sometime he becomes insomnia.
