I've done something a few times over the past few months that I would never have dreamed over doing 10, five, or even two years ago. I've attended events completely stag. And let me tell you something, it ain't so bad.
Instead of focusing on what you don't have -- bring your awareness to what you do have. Friends, family, a job, your health, freedom to see whomever and do whatever you please, the ability to be of service, etc.
