The world does not exist to provide you with enjoyment. If you can make a living doing what you love to do, like many of us here, that's a fantastic added bonus but realize -- it isn't the nature of life to be able to do what you enjoy 24/7 (or 8/5). This is why we have hobbies and relationships and recreation.
The expectation that life will be working 9-5 at a job you love then coming home to a dream version of your domicile of choice and a wonderful spouse/partner/dog/cat and spending your evenings drinking tea/coffee/wine/beer/whiskey debating politics/technology/art/music/literature while gazing over a picturesque sunset/oceanscape/bikini model/forest and sighing gently over how great everything turned out -- that expectation destroys happiness. Life plays out roughly according to the choices you make and is colored by luck. You can change your level of fulfillment by adjusting your expectations or working harder/differently or both. This might sound a little eastern, but what I think we need is a dose of gratitude. You're (probably) alive, (possibly) healthy, (presumably) not living on the street, (hypothetically) employed, (likely) have one or more people in your life who love you... be grateful. I expect this point to be misunderstood, but note for the record this is not the "things could be worse!" argument. It's exactly the opposite argument: "look how good things already are!".
So you work a job that isn't exhilarating? So what. Your job isn't your life, your life is your life.
