I learned how to play back in 1990. There was no such thing as youtube. I used chord charts and listened to my favorite bands and tried to figure out by ear which chords they were using. Then, I joined a band and there was a guy in it whose older brother taught him to play. He knew more chords than I did so I learned from him. Then I started writing my own songs by the ripe old age of 13. If I were to learn now, I would absolutely use YouTube. I would search "how to play ___" and put your favorite song in. Force yourself to learn it. One of the first songs I learned to play was Ziggy Stardust. It's not a super simple song, really. I then learned to play All the Young Dudes, -even more difficult. But I forced myself to learn and I practiced for hours and hours each day. I loved it. Still do.
