I planted it in myself, I entered the world of gambling, I must have a goal and retire someday, I must really think that a business, project or own business is very dreamy.
I think your friend has a perfect life goal, stop gambling and do business, that's something that needs to be supported.
They are some persons that doesn't have any other source of income than gambling. This people even use the money made from gambling to establish and sustain other businesses. Gambling itself is a business, it all depends on the way u do it. I think #a different business will be the right word. Gambling only seems to be a wrong business to people who uses wrong strategy.
