* If it involves an investment of money,
* If there's an expectation of profit,
* If there's a common enterprise, and
* If there's a reliance on the effort of others.
This is true and for me it is because it is an investment therefore we are expecting something in return. If we are not paying attention with our investments it's just like wasting money in gambling as you only need luck in there but with investments it's different because we need those criterias above to make our business successful.
I can see a lot of investments here in my place that owners do not think about it's importance and then the next time I heard about their business they became bankrupt it is because they do not fully understand what they are doing.
