Just put the web sites that pull you in most in your hosts file. Have them point to a site that reminds you how undisciplined you are being. Swap it out when you want to be undisciplined.

Very cheap online math lessons. I passed the CSETs 20+ years after high school math after a few months with these online classes. They solve many of the problems in several well known books that you can buy and work along with. The teachers were very good.

If all cars on the freeway drove with this technology on a crowded freeway less cars would fit on the road and traffic would slow. It seems the results would be similar to the results if everyone actually left n car lengths between them and the car in front of them when going x miles/hour. It would be safer, but because of the huge buffers between the cars, significantly less cars would fit on the road. I am no traffic expert, but it seems to make sense, and I don't think anybody mentioned this. Traffic experts, please reply.
