Happiness is over-rated. Strive for contentment, security, and well-being. If you can't ever be happy at all, you may have a deeper issue, but what you're describing sounds like 99% of people in our modern technology-driven hell. If the modern world makes you feel like jumping for joy all the time, you're either insane or delusional or retarded, or maybe the perfect combination of all three. Or high, I guess.
