The goal of life is happiness - right? We can all agree on that. So the thing to figure out is how to attain happiness.
What I have found is that the less you judge things, the happier you are. In fact, the only way to be unhappy or to suffer is to judge something as bad. Like in this article - a lot of judging of things that are "bad."
If you eliminate this one thing - judgement - then you are happy. Always. So this is the trick for me - removing judgement from my life. Meditating has been a good practice of it.
