Be as ambitious as you can with your writing. There are many writers I have come to know have very ambitious goals.
Some of their ambitions are to make the amount of money they earn at their full time jobs. This ambition for them is to leave a job they don't like behind to replace it with a freelance writing career they can support themselves and families on.
Others have an ambitious word count to meet each day. They have set this goal because they work several freelance writing gigs both on and offline. This ambitious goal also includes writing books in many fields.
Am I ambitious? Sure.
My ambition is to stay as a freelance writer for the rest of my working career.
