1. Spending your money on unnecessary items immediately the money arrives. Trying to prove a point to people by living a standard that is above your pay grade.
2. Live on one source of income. Everyday of our life our responsibilities and challenges keeps piling up accumulating without consideration to our financial capability. The economy and cost of living continue getting worsen. So in order not to be able to beat this piling settle comfortably on a single source of income flow.
3. Become an extremely cheerful giver/lender to friends and family. A wisdom quote I read somewhere said, "if you want to lose your friends and family lend them money". Keeping doing this and you going to be successfully poor.
4.Learn how not to mind your own business, making every events around you your concern even when it doesn't affect you. It's a nice way to make cool enemies. Etc.
I trust you all get the sarcasm as conveyed.
The "living on one single source of income" is the biggest mistake that I have seen people make. I mean, seriously, why would anyone put all their eggs into one basket (their job)? What if they lose their job? A lot of people seem to think that they cannot lose their job because their boss is such a nice guy or because they are so important to the company because they have been working there for so many years...
But the reality is, no matter how long you work at your job, if your company decides you are not needed, your loyalty means nothing.
