I disagree, I think a successful writing voice involves reading a lot of different styles and picking the elements that really speak to you.

I disagree respectfully. Before I write anything substantial, I re-read the few books that I really like to let me subconsciously absorb their elements. If I read modern journalism right before I write, whatever I write will be just like modern journalism: bland and boring. At least for me, there is a very large but temporally proximate influence between what I read and what I write.

Reading selectively makes sense, but I’d argue there can still be value in critically reading content the style of which you’d rather not emulate directly. For one, you may not always have a choice if you need to research something specific and there’s no high quality source available. You can also learn to pick out distinguishing characteristics of modern writing in order to subvert popular convention or adjust (not abandon) your style to be more accessible for the target audience.

It requires writing a lot, more than reading a lot.
