Very interesting write up. I wish people can actually avoid all the mistakes listed here. But it is almost impossible as one may be guilty of breaking at least one. But this would act as a voice of caution.
First of all, humans are made to make mistakes and they are always becoming expert in this field. So dont just worry nothing is there to harm them. Money is always a trouble and whenever it sticks to anyone, he becomes involuntarily jumped in trouble hub. Better is to learn how to stop making big mistakes and how to tackle if you have made one mistakenly.
