Getting into the world of web design requires a keen intellect and lots of free time. I say this coming from experience after recognizing my slumps of creativity which directly affect my workflow. The more you can stay in tune with new skills and techniques, the more you can develop a passion for one specific area. Other designers are often willing to share techniques and tips related to dozens of topics from iconography to typography.
This rule applies even more so to freelancers who don’t always have new projects coming onto their desk from a studio. You need to keep your skills relevant and the following books are a great place to start. All of them are available for digital download while some also offer a print version. Take a look over these titles and see if anything catches your attention.
