I have quite a bit of time to train with my guitar. My question is about the amount of chords one should learn at one time.

At the moment I'm learning A minor, E major C major and G major. for about 15 minutes each. I also learn to change from A minor to E major and vice versa for 15 minutes. The same for C major and G major.

I started learning these chords instead of the easy chords because using the easy chord seems a bit of a waist of time (just my personal opinion).

I just wonder if I'm learning enough chords or else too many chords a day. How do most of you learn your chords.
