Suggestions to improve my copy writing skills.

Practice. :)

Accept that, especially at first, your rough drafts are always going to suck.

I mean it. Every writer, even professionals with years of experience, gets that sinking feeling sometimes when reviewing their own work. The professionals have just learned how to get past the feeling.

Instead of focusing on the suck, recognize that you now have an opportunity to improve your writing. Learn how to self-edit and revise your rough drafts to make them better. Get outside help from an experienced editor if you can.

Learn some basic forms, like Pain, Dream, Fix:

This isn't common advice, but practice writing in a demanding poetic form, like haiku or sonnet. These force you to use direct, concrete, economic language to express an idea.
