It will take you forever to write 750 words if you worry about format and editing while doing the creative stuff too. Most people recommend separating the two actions.Get comfortable with having tons of typos and your writing being mostly nonsense. You have the option to edit it later.

Don’t Worry About Editing

Come up with trackable goals like a number of words or pages per day. The specificity is important because being able to measure it allows you to keep track of your progress and better change your behavior.

Set Accountability Metrics

If you have a friend who’s also a writer you can challenge each other to write in different styles and with writing prompts. He can also help you as an accountability partner.

Be Accountable And Make It More Fun

Keep a notebook of writing prompts in case you run out of ideas or want to leave something for later.

Register Prompts For Later Days

Keeping track of streaks is a very powerful tactic for developing any new habit. Knowing that you have consistently succeeded for a number of days helps you push through the days who are unmotivated.Other ways to foster regularity: writing in a different style or genre, and doing your writing first thing in the morning.

Make It a Regular Practice

To build a habit of daily writing, try to get three pages of writing done every day. It can be about anything and it’s important that you write all without editing or censoring.Daily writing can be used to clear your mind, think out loud and troubleshoot problems, thoughts and anxieties. But before you start, figure out why you personally want to write more often as this will help push you forward when things are tough.

Writing Daily 

One of my New Year's resolutions for 2014 was to write daily. I'm happy to report that I only missed a total of three days in 2014. I'm currently on a 250-day writing streak, and it's become kind of addictive [edit: at 812 now, a year and a half later].
