Holly told me she started writing content in 2011. At the time, she still worked a full-time job but created content online part-time to supplement her income. Over time, she was able to double and triple her rates until she could quit her full-time job to write. These days, she makes bank as a freelance writer and teaches others to do the same via her online course, Earn More Writing.
