That's very true. Learning from our experiences is what makes us stronger in the long run.
I have personally lost a lot in gambling and trading and this has made me stronger. So even when I lose the next time, I don't care much about the amount lost.
On the other hand, I never gamble/trade with larger amount. Only gamble for fun.
I also used to gamble quite a lot and lose on trading too. However, it must be borne in mind that the fact that you are losing it can be completely different money. It's one thing when it's honestly earned money, another thing when it comes without much difficulty, for example, an inheritance or, by the way, tokens received in 2010-2014, when they were worthless. I think that when you lose money in the game, the reaction also depends quite strongly - the one who got the money without difficulty can laugh more. And who honestly earned money may not be so funny at all.
That's a really good point. The source of money used for gambling does make a huge difference.
Sometimes I use the money from airdropped tokens for gambling and often lose them all without any bad feelings.
Sometimes I use my earned money for gambling and lose it and then get a little sad.
But it's all in good spirit. Gambling is meant only for fun.
Also, another thing is that it doesn't hurt much when we used profits earned from gambling itself to gamble more and lose.
For example: If I lose the $10 I deposited for gambling then that would hurt me a little.
But if I had gained 3x profits from it and then lost $10 then that wouldn't make much a difference since I would be in profit anyway.
