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.
Like Airbnb, becoming a ridesharing driver for companies like Uber, Lyft or Sidecar is a way to join the shared economy. And though it is not technically earning money from home, it allows the same kind of flexibility and it is a way to use an asset you already own (i.e. your car) to make money. There are things to keep in mind, though, about driving other people such as whether your car insurance will cover you and how you pay taxes on your earnings.
