To lose weight: Burn more calories than you consume.
To build muscle: Work them repeatedly and consistently at an increasing resistance.
It's really that simple. Yet millions of books, videos, pills, machines, programs, etc... have been produced to give you the impression that it isn't... and line the pockets of those promoting that impression.
My laptop is acting badly. It seems like it's the vid card... or maybe just the vid drivers. It's funny to think that 5, 10, or 15 years ago this would have freaked me out. I would have felt lost and frantic until it was back working perfectly again. I'd ignore everything else, drop all other concerns, and probably wouldn't eat or sleep until I hacked a solution and was back in business.
Now I just think: "Oh... Bummer. Now I'll just have to surf the net on my phone... or XBox... or PS3... or one of the other computers in the house... or go get my work laptop..."
