I would argue that no one spends their time trying to be unhappy. At the end of the day, everything we do is for happiness. It could be writing for freedom of time/location, or working 12 hour days for 2 years to make that promotion. We do it because it will bring us happiness. Or we at least think it will.
The end product might not bring us happiness. Money is well known not to be a miracle-cure, just as getting a girlfriend does not always end well.
But does that mean we are wrong to aim for these objects/relationships in order to achieve happiness? No. You weren’t to know before you got there. You took a risk. Good job.
