When I was little my mom bought us guitars, and after wasting money on lessons for my older brother I had none, and never knew what to do with mine.
At 20 I had an unfortunate 'windsurfing accident' which resulted in a deformity at the end of my right index finger. I used it to confirm that I could never play guitar.
An optimistic friend suggested that in fact it would be good therapy for my injury. Then I was asked on a job interview if I played an instrument.
I had many friends who played and who showed me chords, and after a bit of a struggle I was playing tunes from beginning to end.
Learn one chord, then another and another, Learn to change from one chord to another, and next thing you know you're playing knockin' on heaven's door. There are worse things you can do with your time.
