What should I do?

I started learning the guitar 4 days ago, and so far all I know is Em and D 6/9(though this is really hard for me to nail within the first couple of tries). I want to know what else should I learn first before I start to practice any beginner song.(P.S. I get a wave loss of motivation whenever I try to play a new chord and I can't get it within the first couple of tries...😭)
