Don't "try" to do anything at first, a sure fire way to become frustrated. Just plan on spending several hours just cliking buttons (& looking at the manual) to see what happens & to learn where the optons are located. Don't bother to learn the keyboard shortcuts if you plan on changing to Carrara, that will be another source of frustration. They replaced the quick "any window zoom" with an animated zoom you have to mouse-about to access. Also can't change camera views "on the fly" without more mouse actions. Another good thing to do is to disect some of those pre-made models in your browser. Jump in on some of those interesting shapes and see how they were made in their respective modelers. Change the envelopes & symetry settings & see how it effects the parts then start moving control points around to see what happens.
