Education/Upskill budget ideas

Hi Team,

I have an education/upskill budget of $500/quarter and would like some ideas on how to spend it. I've been a CSM for 7 or 8 years now and would consider myself a high performing IC with leadership ambitions.

I've taken SQL lessons, public speaking, read a number of business books, and writing classes. My initial thought was to take a CSM math class, but I couldn't find a course that was focused on CSM data. 

What have you read/learned that has stuck with you?

Thanks!

Paul
