If i have a profit in a particular game i usually stop in the game because i believe in playsafe. You know you dont the time of luck you have sometimes Its short and sometimes its long. So to be able win the game playing safe is must. If you see that you get profit goal then stop and play again tomorrow.
yeah some people beileve that when you keep playing without have a break time you would get stressed and once greedy takeover yourself then everything just ended early , everything you have got previously could disappear faster than when you get it. better to looking for your luck in different time and collect your winning even for a while.
