This reminds me of my coworker. I hear it at least three times a week, "I'm going to start eating healthier and workout every day, starting next week." It's always next week. And when I ask if he worked out last night, there's always an excuse. We both get home from work at 5:30pm, and he is usually up until 1:00am, yet somehow there's never enough time to work out. Of course he had time to watch this program and that program.
I wouldn't care if I didn't have to honestly hear this multiple times a week. Get serious about it, stop blaming everything but yourself, and just do it.
