I disagree that you should care about your own happiness. Happiness is not a meaningful goal unless you are willing wrap it in nonsensical notions like "actual happiness."
Actual happiness? How is that different from happiness?
My recommendation is to get good at _making decisions_. That way, should happiness be needed, you will be better able to produce it. But if you need something very different, you will be prepared to produce that, too. Happiness is just too myopic and selfish. Good decision-making will often result in happiness, but it's not the sole justification for it. (It will often result in unhappiness, too.)
Talking about long-term entropy isn't a reliable way to make decisions. If we think of 'meaning' as "that which separates signal from noise", you would be saying that -- eventually -- we will be unable to separate them. But we don't live in a reality in which that is the case: we can separate signal and noise right now. So arguing from that point is an argument from fiction. It's kind of like saying "we shouldn't build technology because someone might make the Terminator and everybody will die." Your responsibility is to make the Terminator first and design him so that he gives out hugs and candy. Or whatever else that is good.
I probably sound overly argumentative about this. You have a good point, I'm just trying to dig more deeply into it. I don't think there is a good answer to OP's concern. I would just say "don't worry, just consider your life an experiment," (as is my approach,) but then 'worry' is just part of the experiment. Maybe worrying about it is exactly what he should do. Maybe he shouldn't be happy. Maybe that's the only way to be a better person.
