One tip: I suggest that you stop cluttering your writing with parentheticals.

If it's worth saying at all then it's likely not actually a parenthetical. If it's not worth saying, then you should cull it. Yours seem to mostly fall in this latter category, in my assessment anyway

Decide what you are trying to communicate and be sure that every word is in service to that message and that message alone. For example, you are discussing the practice of writing. That's why I'm in this thread, as a reader. In the middle of a sentence about finishing your novel, you mention via parenthetical that you're looking for an agent. Maybe the intent here was self-promotion -- you hope an agent or someone who knows one will read this -- fine. But if you can't decide and plan to use a parenthetical instead, know that the reader will be paying a dear cost: the sentence containing the parenthetical will be substantially more painful to read. Subsequent uses will be worse.

By that second paragraph, you blew your parenthetical budget, and yet you went on to deploy three more. Parentheticals need to be vanishingly rare as they are an eyesore. Yes, if you'd like to die on that particular hill, you can use them with stylistic intent. Go for it. But for the reader it will probably grate.
