The subject of survival is a big topic and the beginner, as well as the more experienced, may sometimes feel overwhelmed by the sheer volume of material that one can learn.
I always recommend frequenting the several excellent survival forums and message boards that are on the Internet. These are run by friendly experienced people well versed in the field of survival. Participants in these survival forums are skilled in everything from bushcraft to firecraft to handicraft. They take great pride and pleasure in helping anyone. Often the survival discussions are lively and informative. If you are interested in learning more about survival, you will be welcomed with open arms into the survival community.
In addition there are a number of excellent books and magazines that cover the topic of survival. The basic ways of surviving have not always changed much over hundreds of years, and very old outdoor survival books contain nuggets of wisdom that even modern day survivors can use.
But it is not enough to read survival books and visit online survival forums. You have to get out there and practice your survival skills and survival gear. Set up a lean-to, build a debris hut, build a fire, find water. Test your skills in a variety of conditions and with a variety of materials. Make sure you would be able to do these very same things while injured or when it is wet or cold or blazingly hot.
The more you learn about survival techniques the more you realize how much there is to learn. When faced with a large task it is often easier to break it down into bite sized chunks. Survival experts have found through experience that the foundation of survival rests on five basic survival skills. Master these 5 basic survival skills and you are well on your way to being an expert survivor yourself.
So discuss, read, and practice. That is the way of becoming a survival expert.
