I enjoy reading my own work writing once I have sufficient distance from it. Going back to a brief or article I wrote two years or more ago, I can appreciate it objectively and decide whether it is persuasive or not. Sometimes I do read something I wrote long enough ago that I can say, "wow, that argument really didn't work, did it?" I find that useful because it influences my ongoing style -- if something didn't work for me, I try not to use it again in a similar context.
