Personal career Development Curriculum

Hi Team!

I have been in L&D for about 3.5 years and fell into it accidentally. I love it and also feel like I have so much to learn. I have been informally mentored in some instructional design concepts by a coworker as well as have taken training in the Articulate suite from Yukon Learning and Tim Slade.  While this has been very helpful, I find there is so much I need to learn. I especially have a difficult time coming up with slide look and feel ideas. I have not had training in slide design or graphic design.

----------
1. I am trying to develop a personal curriculum to keep getting better. If you were helping a relative beginner, what skills would you recommend they learn and in what order?
----------
2. What recommendations do you have for learning to design beautiful slides and layout look and feels?
----------
3. What are your favorite resources, courses, etc...?

I currently have access to LinkedIn Learning and just purchased the books Slideology and Visual Design Solutions.

Thanks in advance!
