Onur Cobanli explains:
Always design for yourself first, design products you need and ready to buy. If you design for yourself, if you design considering your needs you can come up with true original and efficient solutions that address to your needs; only a person who is seeking for a product could imagine best how that product should be; remember Plato who says it is the doctor that could kill easiest, and likewise it is the person who suffers from lack of design could design the best.
