I'm still searching the cure for lazyness.
However, I found some starting hints:
1 - Leaving your bedroom is a good start. I kept my computer in my bedroom, using the bed as a seat. It doesn't work. Really.
2 - Don't stop the music. Yeah, music makes your mind work. You can't think if you keep watching the ceiling. If you at least is dancing or thinking about the lyrics or listening at the beat, you have a better chance of getting some work done.
3 - Turn off any instant messengers you have, that's obvious, if you keep chatting around, you get nothing done.
For now, these are the hints. They're not 100% effective, but they're helping me a bit. I shall be adding more results, as they appear. This is my number one problem right now, I'm serious about solving it forever.
