Initially, letting go losses Is a general advice for every gambler.Personally,the first thing I learnt as a gambler is learning to forget gambling losses as fast as I can because of the dangers alongside it.For some Gamblers,first losses or losses entirely becomes a mental stress and heartbreak but it's so essential to never hold back gambling losses, it's too much of mental/emotional wreckage.
And the after effect can go wild if you keep remembering your losses you might chase for it and lose more, the point is you need to let go to prevent getting more losses if you try to win everything back. Though most of those who failed to recognize high potential risk that can happen with a single mistake with your decision making instead of forgetting a portion of your savings you might regret trying to win it back as you may lose more.
