I hear this sentence quite a lot nowadys: Everyone is reposible for their own happiness. In some sense it has a grain of truth it in. But mostly, it's just absolute bollocks.
Where did this idea come from? The buddhist tradition and the Mindfullness movement that derives from it states that you should seek happiness not from external factors but from focusing on your inner life. You can't base your happiness on hoping things turn out well. Even if you could affect the outcomes, things are never permanent and this kind of base for happiness is ultimately fragile. Most importantly you can't expect (or demand) anyone else to make you happy.
With all things stated above I whole heartedly agree.
So, that means, then, that you are reposible for your own happiness, right?
No it doesn't. Really, you're not.
What's so profoundly wrong with that idea is this: Being responsible for something implies moral failure in case of not being able to fullfill that reponsibility.
And actually you are not required to be happy.
Not by you. Not by anyone else.
