Inner poise
I suppose that when you start listing the good things with being alone, it's time for you to look for not being alone anymore, but... good thing with being alone is the whole world of possibles ahead. It's the peace of mind brought by the easiness to make your own choices. It's the calm I thought I've deserved.
If you're not single, you're not supposed to believe this, by the way. You're meant to enjoy the happiness of having found your soulmate. If you start believing I'm a happy unmarried 27, you're doomed - I know it, I've been here before.
Maybe I'm just going to have my head in this happy cloud for a little while, then I'll see the dry land again. Maybe I'm just being one of these chick lit heroines, getting back on my feet after every little moment of sore pride. It doesn't really matter, let me enjoy this while it lasts.
