I started as a part-time freelancer and didn't know what to do. But the resilience and commitment to meet the deadlines with a good job are the most fascinating that I believe that the freelance has to give to our clients. But we have to be careful not to drop the earnings bar too low. Your work has value! You have to know how much you can discount in your project earnings.
Yesterday was all about what graduation you've had. Today is about what you can do as a person and being evaluated just by your professionalism. With freelance, we lose that blind moralism that a person with studies is better suited than experienced professionals without them. Both have values both show their work equally: the client decides.
Sorry about this long answer :)
