Take goals seriously. A twenty-year study involving students in a certain Ivy League university in the USA traced the lives of one graduating class. 3% of that class had their own written goals at the start of the study. By the end of the 20 years, that 3% who started with written goals and plans were worth more financially than the other 97% combined. They also reported more satisfaction and joy with their lives.
