The most important thing is to get input — input that you like

and care about. Although reading is the fastest way to learn a lot of English words and grammar structures (especially if you are a beginner) you may have good reasons not to read a lot. Maybe you are excited about spoken content — a podcast or a TV show — rather than written content. Maybe you are too busy to sit down with a book, but can listen to your iPod while jogging. As long as you keep getting input, you will eventually get results.
