When a person is in trouble - be it financial or personal - they learn and make their decisions.
But - having said that - its also good not to be greedy for money and its also not good to have money on your mind all the time. this lust is crazy - try to avoid it as much as possible.
I think greed is a also one of the major factors on why people get addicted to gambling.
And yes, I think you’re right when you say we should all try to not be greedy for money and definitely not good to have thoughts on how to get money all the time. The lust like you said is really crazy and it can make people do crazy unimaginable things in the quest to acquire money and more money. In some cases, during this mad lust in acquiring money, people may turn to gambling and then addiction slowly and steadily creeps in.
We shouldn’t let money control our thoughts and actions.
