yay to new hobbies! best thing is to try not to get ahead of yourself. start with basic songs with easy 4 chord progressions. get the hang of strumming, switching hand positions, etc. then you can start to level up to bar chords, tabs, finger-picking, and more! ultimate-guitar.com and youtube tutorials are especially useful in these stages. but be patient with yourself, and enjoy the time you spend with your mind entirely focused on the thing in your hands and not roaming elsewhere. what a treat:)
