Do designer need a client to start designing?

Creating MI from scratch, ambulance just based on an idea (well maybe that’s what i only need), sickness is hard. Not having actual client except maybe myself makes it difficult to start the project. What actually makes me move? Is it the desire to get the website up, or the pressure from Laurene, my supervisor? Perhaps Laurene is my client too…
Is it the purpose of having this website that moved me? Until now i still can’t define why… maybe later… or perhaps not…
