IMO the most valuable is knowing when to walk away from a side project. Start a side project or hack on an idea you enjoy but when you start becoming stressed by it or realize it's not panning out as you expected, take a breath and kill the project. Harder to do with work projects but still possible. Scope the MVP to somthing that can be "done" and then allow management to iterate and see if this is the direction they want to go in.
