Coming back to the possible relationship to the entitlement of Gen Y (and maybe anyone when they're young)...
If you have too much of a Fixed Mindset, you probably undervalue experience. You likely think you have just as much ability to do a job as someone with far more hours notched up.
A Growth Mindset, on the other hand, celebrates building up experience over time. It encourages you that you don't need to be at the top-of-the-ladder from the get-go. There's nothing wrong with starting small and working your way up slowly.
