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.
Know the difference between an asset and a liability. The dividing line is whether it puts money in your pocket, or takes it out. As much as you love your home, for instance, it is a liability rather than an asset because you put more money into it than you get out of it (unless you're flipping it or renting it out). Whatever money you save, invest it in assets such as stocks, mutual funds, patents, copyrighted works--anything that generates interest or royalties. Eventually, you might get to the point where your assets are doing the work for you, and all you have to do is sit there and make money!
