Learn what? What template? You need to be much more specific.
I had a bunch of AE templates and thought that I could learn AE like I did Photoshop and Premiere Pro -- get my feet wet and plug away at it.
AE is not at all intuitive. I purchased Classroom in a Book and after about a dozen hours I knew enough to use a very simple template.
If learning Premiere Pro is like learning how to apply a bandage, then learning AE is like learning brain surgery.
