Envy.

I see people doing amazing things with their lives and I become so jealous of them.

What's holding me back from being one of those people? I can't say that any of these things are impossible for me. I'm too lazy, too scared, too complacent to stir things up in myself. It's terrible. I always frown on people who complain but don't do anything about it, and I'm one of them. I really need to wake up and get out of this rut that's lasted for 19 years.
