Having feedback can help you spot issues you tend to overlook. Also an uninvolved opinion also prevents you from investing on something that is bad because you are emotionally attached to it.

Writing in different styles and formats lets you find and hone aspects that apply to multiple formats. You also get to exercise your skills as the writing won’t come as easily as it would if you were writing in the style you’re comfortable with.

Experimenting with different technologies, methods, environments, and schedules is really helpful in determining what works and what doesn't and can increase your efficiency.

Researching, note-taking, brainstorming, outlining, and drafting are particularly useful for the initial phase of writing. 

It's easy to unintentionally keep researching or reading or tweeting and not writing to the point it becomes procrastination. To fight against that, limit the time you spend on those activities and stop subscribing to sources of content that don’t add to your work.

Feedback is very important. Having someone read over your writing can highlight issues like typos or grammatical issues,  and help you to clean up your work.

New formats are exciting and scary, and definitely worth doing if you want to stretch your writing muscle.

Try new kinds of content (articles, opinions, announcements, etc.) and play with different formats, to see what works best (images usually make a post more interesting, regardless of format).

Try different methods, environments, and schedules in your quest for a workflow that suits you.

Experimenting is really helpful in determining what works and what doesn't.

Reading and researching a post are the most nefarious distractions. It's so much easier to keep researching or reading or tweeting and not get around to putting words down.

Be open to reading more fiction, more nonfiction, more research papers, to help you add knowledge to your life.

The more widely you read, the more chances you have to generate new, creative ideas or come up with interesting angles for what you write about.

It will help you with keeping track of quotes, books you've read, expressions and words you like, interesting concepts, and ideas you have.
