You definately need to get camtasia and record some tutorials! I just got it, haven't looked into it or at the tutorials yet as it's 3am, but just looking at the interface I'm confuzzled!
Trust me. Its took me 4-5 years to get as good as I am now
I hope you learn alot faster!
Things that help modelling:
Meshsmooth (took a while for me to find), Chamfer (Smooths meshsmoothed corners if you still want a corner, where meshsmooth would usually curve it), and not forgetting Light Tracer, or Global Illumination.
And polygon modelling, creating holes, in surfaces without using Boolean.
Yeah, if you ever get around to doing a tut, just make say, a PC tower, just not as fancy as the one you just made. Focus on the dimensions mostly, I dunno =[
