Although I'm interested in all branches of design, it's subject is more important to me.The subject must be meaningful.
For me, solving a problem of people is more significant than just creating repeated beautiful objects.I fancy subjects related to design for disability, for education, for children and sustainability.
Besides, the process of design itself is the matter. It's a way of growing; not only for the result but also for me as a designer. That's the essence of enjoyment in design.
