We just published an initial version of the Leadership resources on the Wiki. This is in no way complete, but serves as a first version to spread the knowledge. At first in the RepsNext process we wanted to create a specialized track for this, but we decided against this as we want all Reps to enjoy this knowledge.
As this is an initial version, please share your feedback below. I would love to see discussions about other good resources we should be adding to this list. Who knows good other resources? Maybe even free workshops others can take?
