Thinking back on the way I treated women as a young adult, I can’t believe I ever got laid. But I did. A lot. Then at 28, I got laid off from my job as an advertising exec. Walking home midday, in the depressingly empty streets, I realized that I had nothing. Sure, I had a few thousand dollars saved up, but I had no one to go home to. No one to vent to. No one to hold. I was alone, and it was my fault because I’d been such a dick for so long. I pledged to change my ways that day, and I did. If you don’t want to end up alone, you have to treat people the way they deserve.
