Do you have any favorite songs? You can start by playing you favorite songs that are basic- that way, you remember your chords without any effort and it becomes natural. I remember the first time I learned the guitar. I was hooked up with the Beatles at that time and I would sit on the pavement for hours trying to master chords their songs. I started out with the most simple song- eleanor rigby which only has C and Em most of the time. After the chords have become natural, I then switched to other songs that uses different chords besides C and Em and practice it until these new chords become natural too. If there is a particular chord that you want to learn about but always forget how to play it, its always good to find a song that revolves around that particular chord. If you can't find a favorite song that uses the chord frequently, then make your own chord progression that involves the chord you want to know about. The Beatles used this technique and I find it really helpful. Hope it helps you too. Keep on rockin!
