It should be noted that the crash course itself provides only the ost basic of overview. It will not, by any means, be your sole guide to attaining mastery. What I have been doing is reading through tons more tutorials on how to achieve specific effects on Illustrator using the tool of the day. I know, for example, that although the crash course’s compound path tutorial taught me how to make a key, it was not the kind of key I actually made yesterday. To make MY key I read that tutorial to gain a basic understanding of the effects, but I also supplemented it with tutorials on how to create a heart, how to create custom swirlies/curly vectors, how to actually save a custom brush so you can use it forever, etc.
Tools take time and dedication (and tons of practice and ctrl+z) to master, so don’t feel stupid about googling tutorials fo the easiest things. They’re only easy once you’ve learned and practiced them. Until then, google away!!
That being said, here is day 10’s outcome.
