Easy chord you should learn first (guitar)

There many chords you can do on the guitar but there are certain ones which are harder than other so you start off with the chord A to the chord D these are fairly simple to learn. Then to G to D,The C chord can be hard to learn so the best way to learn how to switch to the C chord is go from the Am to C as these two chords are basically the same thing just one finger is in a different place. To learn G use Em as these are very alike aswell.
