How to Create a Learning Curriculum for Mastering Clay and Adjacent GTM Tools

I’m seeking advice on how to continue my learning. I learned the basics of Clay (Clay University) and completed the AI Skills Cohort. I now have to master Clay and adjacent softwares (n8n, Instantly, a crm etc.) Many have suggested to me that the next step is to analyze pre-built Claybooks and templates. I tried this but was overwhelmed with questions about the templates (why does this column exist? why doesn’t this cell run? why does the output message look wrong?). I’m could start experimenting with the adjacent softwares (Instantly, n8n etc.) but I’m not sure I have the right project ideas to learn optimally. In short, can someone suggest a curriculum or offer advice on how to generate one, as I work toward becoming a GTM engineer. Many thanks!
