Losing and winning is just part of the game, we need to be open on both outcome. However, there is a saying that you need to seize the moment, if you are lucky continue gambling and win it all, but don't get too greedy.
If you get really lucky on a slot, I would always stop and move to another slot or simply stop the session. Whenever I score a higher multiplier on a game (x50 is high for me) and I keep playing on the same slot, I never seem to get any more higher wins... Because as you know, your luck can turn around very quickly!
