It doesn't mean trying to figure out how to create advanced content, with absolutely zero prior knowledge of the subject.
That's why step 3 was the tutorials..
And whether you (or they) realize it or not, every single SL user who creates content DOES absolutely spend weeks studying.
Yes, it's that incremental, curiosity and desire driven style of learning I'm suggesting.
you don't just hand him a violin, and say "Here, watch this video to learn where to put your fingers when, and you'll get it in no time."
Sculptie making in Blender is pretty much:
1) create a starter sculptie from the menu
2) move the mesh until it looks like what you want
3) pick bake sculpties from the menu.
Once you learn how to move things around you can make sculpties. It's more Rockband guitar than violin

You don't approach the instrument with any particular piece of music in mind.
Sure you do. It's that dream of Mendelssohn that motivates our violin player through his studies. If Jolly was asking how to make his own 3D feature animation, then I'd be on your side about studying his entire 3D application, but he just asked about sculpties.
And if you want to make stuff with a 3D modeling program, you learn 3D modeling, not just the particular stuff you think you want to make today.
And if the stuff you want to make today happens to correspond to a nice simple first 3D modeling project?
Tomorrow brings either "Thanks, I'm happy" or questions driven by curiosity and a desire to improve.
It's a different way of learning than structured study, but no less valid.
