Dear fellow MT-enthusiasts

Are there any podcasts on MT about how to avoid being taken advantage of in a network?

In Mark's latest Things I Think I Think he referenced an article cementing the value of an open network.
Earlier I had a large network but I chose to make it smaller as I focused on the beginning of my career instead. Back when my network was larger my willingness to give give give often got taken advantage of (I'm a high S).

Best regards
