There are three ways that a person can live: live and work normally, live and work dedicated to some purpose, or withdraw from society. In religious terms these groups correspond to the laity, the clergy, and hermits, but secular society can divide this way too. These groups depend on each other, and each of them can do good, and I think it's a mistake to say one is absolutely better or worse than the others.
Nevertheless some people are better suited to one group over the others. If you think one group is better for you, then you should move into it. That doesn't mean the people in the other groups are doing things wrong though, they're just doing things differently from you.
Suppose you're a person with the skills to work at Google for a lot of money. Google is ethically complicated, but they do some good things for sure. You could work for them, make a lot of money, live moderately, pay your taxes, take care of a family, and donate to charity.
You could also work for much less money for some organization that only does good. You're definitely making things better at work, but you have less of your own resources to put toward taxes, family, and charity, and you're consuming the taxes and charity that the first person paid.
Or, you could withdraw almost entirely from society, live some place extremely cheap, do some freelance technical work for a few hours a week or maybe become a short-order cook at a truck stop. You're not really making things better on any large scale, but you're not making things worse either, and at least you aren't consuming resources. You're also free to write or make art that inspires and leads the first person to donate and the second person to work under their market value.
All of these are good options, you just need to find the one that is the best fit for you.
