Hi ,
I was majorly overwhelmed when i started 3d & I have no art experience or teachings whatsoever so it was a lot but I really wanted to learn to model & create some cool scenes.
I figured out what I wanted to use Blender/3d for-what do you want to create? In my case it was mostly architecture & landscape scenes. Once you decide that then your path will likely have a much smaller scope and therefore much less overwhelming. If you decide you want to do everything then figure out/choose the thing you want to do the most now and do the learning flow /tutorials that match that . Stay focused on that learning path so you get some confidence & feel progress. I recommend doing some Blender every day at least 5 days a week personally even if its only 30 min or an hr. Don’t let yourself stop for a few days or even a week or more because it kills your momentum of learning . I did that a number of times before I committed to learning Blender & it was really hard starting back up as you have to build momentum up again and its very hard. The cgcookie site is wonderful as is the Blender guru site & his beginning tutorial series . Best wishes!
