If you're less than happy with your life -- either personally or professionally -- the problem isn't education, or upbringing , or a lack of opportunities, being held back by other people, or even bad luck.
If you're unhappy, the problem is you. While approximately 50 percent of your happiness (your "happiness set-point") is determined by personality traits that are largely hereditary, the other 50 percent of your level of happiness is totally within your control: your health, your career, your relationships, your interests and pursuits...
If you're unhappy, you have the power to change that. Since the best addition often comes from subtraction, start by deciding to do these things:
1. Never equate acquisition with satisfaction.
2. Never mistake political gain for achievement.
3. Never let the fear of disapproval or criticism hold you back.
5. Never wait for that big idea.
