I do not think what can be spoken so. really directly all clever are rich and is not present among rich silly people... and by the way, there are a lot of very clever people who are poor. just they are not fixated on material benefits.
There's possibility we can make mistake if when we do something without thinking and surely cause it us a lose our money. Sometimes we become silly in decision that's why the outcome close to poverty or lose a lot especially when we do investing. But we can prevent to belong to poverty by thinking what the best thing do or having a clearly mind before we decide.
