There are a lot of network marketing mlm events out there that help you enhance your skill set, and build belief, but a few of them rise above the rest.
Besides attending your company specific events (which I highly recommend you do), here are a few events you should take a look at if you really want to grow in a big way:
Go Pro Recruiting Mastery by Eric Worre
Mastermind Event by Art Jonak
ANMP by Curtis Broome
Top Earner Academy by Ray Higdon
