As far as getting instructions it is very easy. Get rid of everything you haven't used in a long time. Have a garage sale or begin selling things with value and take in some money. Donate the rest.
Rent tools or cars when they are needed instead of owning them.
Living with less things takes up less space. It might be beneficial to move to a smaller place or rent a room like I do.
http://www.tosimplify.net/ This is my favorite blog. It isn't an instruction manual. It is an entertaining view into a life of a musician that lives in a Volkswagon Vanagon van. He started in a Ford van with a high top. Then he moved into a Class C small motor home. He downsized to the VW within the last few months. He is happiest in the smallest van. He custom built the interior. Read his blog from the beginning to understand his process and motivation. He is self employed as an arranger. He arranges the music for the TV show "Family Guy." He also performs as a session player on recordings.

http://zenhabits.net/minimalist-fun-...ngs-challenge/ I visited this site and didn't find it as entertaining but there are some ideas here that many people like.
I know of a couple of guys with blogs that live with very little. I've only recently come across them and can't recommend them yet. One guy is walking around the world pulling a cart with his things. He's been doing it for fifteen years. The other is traveling around the world with not much more than a back pack. The first guy is doing it to prove something to himself. The second guy is doing it because he likes traveling. He recently formed a company taking people on tours of India.
