When it comes to happiness, I've heard it was a modern day invention. It kind of makes sense doesn't it? Happiness was only truly marketed like it is today in the past 50 years. Sure they sold products before that to make you happy but it wasn't as aggressively marketed as if it was going to run out or that it had and their warez was the cure. The truth is, happiness is a state of mind (duh) but it's also about attitude.
The quick answer is: Don't give up on your dreams, chase them; Stop Being Negative- it serves No one, especially YOU; Be responsible, take responsibility for your actions and life (hardest one for many to overcome!); Stop stagnating!; Stop trapping yourself in a job you hate; Don't be a dreamer, be a dream chaser, create paths for others don't always walk the ready made path; Accept Change, it's the only constance!; Stop refusing change based on bad excuses that aren't even your own!; Always educate yourself- this is resource planning!; Stop letting others dictate who you are, Take responsibility for your life (warrants repeating). Now Let's Break those down.
