Gil Fronsdal wrote an article on Buddhist practice as a way of learning to benefit both self and others. We can express this mutual benefit through our work, but also through the choices we make to support and benefit ourselves and others. You can find that article here: A Life of Mutual Benefit
An article by Krishnan Venkatesh also makes the point that, while our day jobs are important, they’re not the only thing to consider in trying to practice wise livelihood. You can find his article here: Why Right Livelihood Isn’t Just About Your Day Job
