When you can make something based on your own desire and ability, sometimes it will give you more self satisfaction. Beside, when you can make something from yourself, then why should you buy it? Perhaps you can get it with less money when you make it by yourself. One of the things that you can make by yourself is the bookshelf in your room. Design a bookshelf is actually not so difficult. You just need some woods to make the bookshelf and some nail. After that you can either varnish it or paint it to get more attractive look. Therefore, you can get your own bookshelf that you can design it by your own ideas.
