I have plenty of examples how gambling helped people to find themselves. A guy from parallel class of my school started playing poker many years ago, participated in offline tournaments, but ended with having a poker blog/poker school/poker team. Plenty of people I know work for gambling industry. If that is not a good side (salary/something that you love to do bring you money and joy), then what it is? There no good side in gambling when a person focuses only on money and result, but skip process and entertainment part of it.
