To Improve, Prepare Yourself For Punishment
A great part of writing and being a writer involves criticism. A lot of time, we are afraid of having our work scrutinized constructively by others that we pass up opportunities to have them take a carving knife to our revered work.
If you can afford a professional writer or editor, pay them to look at your work and give you critical feedback without sweetening it. The tougher the criticism, the more helpful for you in the longer run.
The narrow road of the publishing industry is full of rejections and criticisms from publishing houses, editors, agent etc and the sooner your mind opens up to such circumstances the better accustomed you become.
As harsh and painful as this reality might be, if you are serious and want to improve your writing, you’ve got to prepare your mind to know everything that’s wrong with it and how to handle/correct them. You’ve simply got to own your shortcomings and work on them.
An alternative to having a paid editor/professional writer – when you can’t afford to – is to find Alpha/Beta readers – (no not your mother, please) who will support you by critiquing your work. Check this link for more writers’ tips.
