Having a partner to discuss with, learn from and teach makes everything both easier and harder. But it's not a substitute, rather it's a complement, to the books suggested above. Easier because 2 sets of eyes and 2 minds will let you make smarter progress. Harder because you have to think about the other person. But this is the good kind of hard.
