I am going to complete agree. Pattern drafting seem to come more naturally to those who already have a strong concept of what is needed in order to complete a pattern. If and when you learn to do some basic sewing and have completed some clothing patterns I highly recommend the following book:
Patternmaking for Fashion Design
It's a text book used in a couple different fashion schools, including my own, FIDM. It's one of the most comprehensive pattern making books that I own, and I own many. The best part is you can literally teach yourself almost everything from this book. Many of the concepts will be done in women's clothing but, there is a section on men, and trust me if you can contour things to fit all the curvatures of a woman's body - honey, you can make anything.
You will learn to make your own slopers which are INVALUABLE! I own a complete set for myself beyond just the basic 3.
I am happy to share anything else you might want to know about pattern drafting whenever you are ready to learn.
