Beginner, Pretty much agree with all the good advice offered so far. I started in my teens, a friend initially taught me three chords A, E and D majors which are probably the best to begin with as they're fairly easy to play and move between, you can play along to lots of easy songs (in A maj)and are all easily modified to play the minor and 7th chords once you start advancing a little bit.

Onr thing which you might want to consider, depending on the type of music you want to play - and more importantly who you know - is to learn some chords in an open tuning, I'd suggest DAGDAD, where the strings are retuned down from the standard EBGDAE. If you know someone who plays in this tuning it's easy to learn some 'one finger' chords quickly and start enjoying the instrument almost from the first time you pick it up as the open chords can sound very pleasant. It might ease the inevitable frustrations in the early stages of your learning curve with the standard tuning, especially once you progress to the harder C, B, F, chords.   Just a thought anyway, and only to be attempted if you know someone who could show you how to retune and where to plant the fingertips, otherwise probably not advisable for a beginner.

Remember - Don't give up , every time you pick the instrument up and practise you will be a better player than the last time you played.

Good Luck
