GUITAR >:D

I've only been at it for alittle over a week, but I already know the basic 4 chords (G, C, Em, D) and I am starting to learn a few other songs using other chords. The songs I know/am learning right now are "Leaving On A Jet Plane" by John Denver, "Honeybee" by Steam Powered Giraffe, "Stay With Me" by Sam Smith, and "That Funny Feeling" by Bo Burnham. I am afraid that if I learn to quickly in the beginning, I will end up burning myself out... but I am also getting hyperfixated on guitar and sometimes its all I can think about until I practice and play to my hearts content. IDK just wanted to jot my thoughts down :P
