Before you give yourself any bad habits it is important to learn the basics. It's easy to learn how to make one or two things... It's like learning a tune on an instrument, if you don't study the reasons why you are playing the notes in that order then you will only ever know one tune.
If you start from the simplest of tasks then you will be able to work out how to do anything. There are many basic 'how to' book available, most of them have some sort of axe to grind (they are often promoting 'alternative lifestyles' or re-enactment).The series of books produced by the British government in the '50s was not intended to sell new styles of tools or change the way people think or work, merely to provide a good grounding in the subject.The exercises in here may be anachronistic but they all teach valuable aspects of technique: The Blacksmiths Craft
Good Luck!
