The problem is sometimes many gamblers are aware of things like this but they don't want to force themselves which makes the situation the same no change and they always blame the situation or even the gambling they do but they don't realize that the biggest mistake is that they can't control themselves properly.
For me, emotions and everything related to impulses is what makes many lose control, It has happened to me and since I know how emotions are handled , it is very difficult to control them For me, it is easier to control the money I have to spend , but it is my way of controlling everything I don't know , for some players it is easier to Control their emotions , but I let my Emotions and impulses out and with Controlled money I give myself this luxury In the end, what matters is to enjoy it too.
You have started gambling by setting your limits, but your emotions will make you forget your limits, many players know very well when to stop or how much is safe to bet, but when emotions are not in control, you can easily exceed your limits. Gambling is a pastime, it is not a place to win money, so just enjoy gambling, and keep it limited to entertainment only, excessive emotions force people to cross the limits, so I would never let emotions go out of control.
