people who criticize are always the ones who haven't achieved more than you have. It's always that way when you have money, they come forward and be on your side but when you have nothing, you are set aside and even discredits your achievements.
it's best to just keep silent when you have money and never show them your success. not everyone on your side is your friend. sometimes they are just waiting for your failures.
I totally agree with you, and there are some people who claims they are our friends especially when we have money and you are spending too but once your money is finished, they will leave you by your to go and meet someone who has money and when you need their help, they won't help you even if they do, they will do that just to mock you or even insult you, forgetting you have once help them, those kind of money need to be avoided and also we should learn how to manage on how we spend our money in order not to fall a victim of embarrassment.
