Just yesterday, fortunately I won on slots and roullete (the anusual winning tha I get from gambling).
But unfortunately, I've been eaten by some greed on me to bet higher, and that's when my wins are cut down slowly nut surely.
I've been playing for a almost half of the day, before, my plan is to walk away already if I already got my winning amount goal.
But I haven't, I continue betting and at the end of the day, I lost almost 90% of my winnings that day. 
Sometimes it's hard to decide what to do, I should set more outlines for myself for this I guess.
