If nothing goes wrong the whole day, then that's your lucky day. But i can never know that. I just let myself decide on thing then if the result is successful or favorable, then i'm lucky. I just analyze the situation then choose a decision with reference, then let my luck affect the result. My point is that it is impossible for me to determine whether the day is on me or not. Its all about luck
Well what if something goes wrong in between the day but you end up winning the rest of your games? I think nobody can determine a good day or a bad day unless perhaps we draw a balance sheet and attempt to statistically determine our wins and losses and draw a relationship between them.
We might not able to determine but we can feel if we are lucky or not, however sometimes we are overconfident and we think we can get it all in just a day.
Gambling is a game of mind and one must be clever enough in order to win, you will last if you have the skill and you develop it overtime, but if you only gamble relying on luck then for sure you will not be consistent in gambling and you will lose in the long run.
Winning for others does not need to be consistent because they are just looking for a one time win that will make them rich, so they try to look for that.
