3. Don't fall into the it's-about-the-money trap
Although having money is way better than not, our decisions about happiness are multifaceted. Some of the happiest rich people are rich because they're doing what they love. Chasing money for it's own sake is dangerous and deadening. If you have the money, but hate your life, your job, your self, what's the point? Having enough money to do what's important to you is a worthy goal. Think twice about selling your soul just to have more stuff and status.
