What software do I have at my disposal, and what software do I need?

I have the full Adobe Creative Suite, which includes all the tools I might need to be able to create designs.
I also own an iPad Pro, and have Procreate for illustration and Bazaart for quick composition edits.

What do I need to learn?

I have a good understanding of most of these tools as I use them on the daily basis as part of my daytime job. I have also been using Photoshop since about 2005, so I have a good understanding of what the software is capable of and how to achieve the effects I am after.
I have recently started using InDesign, but I have a lot to learn in this department. I hope I can do this by using the software more, or by doing some crash courses that will help me understand the software better.
