If doing anything no matter what with bad mood and low dopamine levels in your brain it ain't going to be successful.
That's why even the rich people need to boost their dopamine levels with good activities travel good food nice cars nice people around them.
i agree that we should feel motivated to be productive but for other people dopamine levels can only result from spending money which is not a lot of people can afford to do so
many people are forced to just work no matter how they feel it is a sad thing but it is what makes you stronger
