Earning money is real hard and it's a no-brainer. So basically what I do is I write down in a diary of my daily income along side with what I have sacrificed for earning that amount.
It is really hard to earn money by this time so seeing your money being lose in a gambling will definitely hurt you a lot. You know what, it is not really a bad thing to gamble but just do limit the time of gambling. Dedicate a little amount of money that you are afford of losing and ofcourse a discipline in yourself so that you will not be so addicted to it.
It is surely very hard to earn money nowadays and losing it in gambling is very sad but how come some can't see that. It seems that some other people aren't saddened by their losses and still continue to spend on gambling. I guess people are thinking more about the possible winning but don't care so much of the possible lose they will incur along the way.
