Many people would like to say it is hard to image some things and create with nothing. They think they have problems in designing. After a long time researching, I find the biggest issue is about their design theories. I always recommend people to get the basic knowledge of design even though it is not their position. It is important to know the styles, colours and others feature for your life, as it can help organise all your life beautifully and reasonably. For example, a good design kitchen can give you more space than it real, or a good sitting room can make your room much larger than before.
