Your heart has to be in it to learn guitar. If not, don't fool yourself. It takes a lot of practice to be decent. But it is very rewarding to learn a song. Everyone makes fun of Stairway to Heaven, but it is a great guitar song, acoustic intro, arpeggios, and then an awesome solo at the end.
If you really want to learn, there are several good YouTube channels that teach guitar.
What type of music do you like? Rock, classical, etc.
Learn to read TAB. Here's a good web site to search for a song you want to learn:
Go to the bookstore and pick up a guitar magazine that has song TABs or look on eBay for back issues of guitar magazines with songs that you like.
Start off with learning the open chords: E, A, D, C, G. Then learn barre chords (E and A type). You'll be able to play a thousand songs just knowing those basic chords.
