That's all that there is to it. Practice until u can play it with your eyes closed and 
you can sing the melody with it.

Am7
 Where you are seems to be
D
 As far as an eternity
G
 Outstretched arms open hearts
Em7
 And if it never ends then when do we start
Am7                        D
 I'll never leave you behind
                  G
 Or treat you unkind
                   Em7
 I know you understand

If you see the pattern here the rest of the song is simple. The chord order is basically 
through out the whole song.
Try to make the high note stand out when playing the riffs.
