The time you spend is valuable and it is a gamble that your time will be worthwhile or not. Not everything should be looked at in terms of money.
When you are not at all looking for money making from gambling then there will be no need of looking for any profitable betting strategy as per this discussion. I agree profit making from gambling is not at all possible still many gamblers keep on trying for that. For them money is everything in gambling and I believe they will never accept for not looking everything in terms of money in gambling.
