Learn how to transition to different chords. One way to become proficient quickly is to learn how to transition between the various chords quickly. These transition periods are often the hardest for beginners to play when they are starting off. The more you practice between switching to different chords, however, the better you'll get at doing it in songs. Practice switching between open chords like G, A, E, and C. 
Hold your guitar correctly. When you are sitting down, there are two main ways to hold your guitar. For a casual playing style, lay the guitar over your dominant leg. On the other hand, the classical method has you set your guitar on your non-dominant leg. In both instances, make sure that the guitar is held close against your body. Holding your guitar properly makes it easier to play and prevents you from becoming fatigued. Play around with both styles and figure out which one is most comfortable for you.
Position your fingers on the neck. The dots on the chords represent where you should hold down your fingers on the neck. For instance, an A major is played by holding down the string on the second fret on the 2nd, 3rd, and 4th string. An E minor is played by holding down the second fret on the 5th and 4th string. Hold the strings down until they are pressed against the neck of your guitar.
