That is much better than treating gambling as a way to have some fun and waste money. But just the same, there is no guarantee that you would turn out successful simply because you are treating gambling as an investment. Remember that gambling is really a business. Money is designed to end up with the owner rather than the gamblers.
But at least it means that you treat gambling seriously. That increases your chances of winning. But that also means effort in making serious analysis before each bet.
Sports betting is mostly depend on analsys and and good knowledge because this is really helpful but still we have chance of lost I personally know many peoples those are living on this and have some good funds in pocket so just try to live in your limits and never go out of your average will also increase your chance as this will go as an investment rather then a gambling.
