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.
When it comes to dopamine it depends on the individual preferences and characters; to be exact dopamine is
Dopamine is known as the “feel-good” hormone. It gives you a sense of pleasure. It also gives you the motivation to do something when you’re feeling pleasure.
some people generate dopamine through good deeds, accumulating wealth or just about anything, An individual should do what he pleases to increase his dopamine, and its not constrained to those you've mentioned.
If you are poor start working with your dopamine and good mood levels first and wealth will follow itself with anything you do.- when someone is happy about his business and going to clients and the clients see the happinness and passion then they want to buy your service or product.
I think an individual should start with a plan and motivate himself to reach the goal of the plan and when he accomplishes that, dopamine will come naturally; feeling pleasure is knowing you've accomplished your goal and you are motivated to reach more goals, and that's where dopamine will come.
