Well, some people think life is this simple, and they keep chasing this elusive concept of "happiness" like a dog chases a rabbit. Some things can't be changed, and some things shouldn't. If something, or someone, is making you miserable, then yes, make a move. But the grass ain't always greener on the other side. Sometimes it's best to stay the course and work through the problems at hand, even though they might be difficult and seemingly impossible to surmount. Hightailing it the other way, again and again and again, thinking that "happiness" is just around the corner, is delusional. Happiness is transient, and it has to come from within. You only THINK this shiny new car or this shiny new job with a bigger paycheck or this shiny new relationship is going to make you happy. But those things never will. Those things are like a drug. They'll give you a rush for a little while; but, before you know it, you crash, and you're even further from achieving inner peace than before. So life isn’t simple. It’s difficult. Accept that and get over it. Happily ever after only exists in fairy tales. But, if you work real hard at self-awareness, and if you disallow external factors to rule your overall state of well being, then snippets of pure joy can be had.
