If both can be run simultaneously and also you can still enjoy social life well then why not run both simultaneously because it means you have 2 sources of income and that is very good for making your economy stable,
If what you're saying was possible then the OP won't have come to the forum to asked for suggestions. Also it isn't always about the money, we have people that value their free time more than any money they can possibly make from stressing themselves. Probably the OP is getting stressed from working his main job since that which is his passive income is giving him more money so he's seeking for recommendations on what to do.
If I were in your shoes OP, I would quit my salary job, reduced my expenses and work on making my passive income more productive. Before, you had your attention divided and yet your passive income was giving you equal or slightly more than your salary job, now imagine what will be the outcome when you have all your attention to your passive income works. I always advise people to chase their dreams and not die working for the system.
But really, if you can still do both why not, yes, even though the income from work and income are almost the same, isn't it great to increase income to add other sources of passive income.
If I were OP I would do both until my passive income can be doubled from now, it can be done with investment or whatever it is that provides passive income every month, isn't it better for the future which may not only be sufficient in terms of financial but it will make us calm because we have many furnaces of income, so if there are already a lot of passive income sectors and it is thought that it is quite recent to stop working and enjoy a good life with family without thinking about work anymore.
