So this led me to ask the general public if I am gambling too much, although this excess didn't affect my finances in any way since I still managed to come out with little winning at the end of the day and at some level, my losses are still below 30 percent of my set out money.
According to what you narrated above, I can't say you are gambling too much, after all, it seems that you enjoy doing it, so why not continue and have fun through it? Gambling is not so bad as many take it to create unnecessary fear in themselves. Like yours, I can only decipher psychologically that you are giving yourself that break because of the fear of either money wasting or addiction. This is in fact very nice and advisable but yet could be relaxed if you realise that you are enjoying gambling more than the fear you instil in yourself.
Also, the good part is that you never mentioned any irresponsible gambling behaviours, and as a fact, you are winning even if it is little. All these point to the fact that gambling is not negative for you, so you do not have to punish yourself too much over it or have hurt feelings that you are going against your plans. Not to mention that the last time was even a mistake, you only forgot, it is not as it is in the case of many people who due to emotion will knowingly abandon their gambling plan. But yours was just about being taken away by the activity due to the fun you derive from it. So you are still progressive in my opinion.
But mind you, a rule is a rule, I would encourage you to be strict about it next time. This has passed, the next could be catastrophic if care is not taken, and the earlier you guard against it, the better. I advise that it is better to relax the rule for better engagements in gambling than to default on it. The breaking of it can only speak of how weak you are in the face of the discipline and self-management we often preach in gambling.
