Sram Rival Brake Bleeding

Curious question.. as I've YouTube and Googled this topic... doesn't look easy! Looks like a pain in the arse.. the reason I ask is that I'd like to do more of my own maintenance and save where I can, due to sprog on route in 3 months. Cheers folks. (Any tips or tricks..links welcome.. but I'm looking at your perspective mainly..easy or hard?)
