In my younger and more vulnerable years my sister was given some advice which I’ve been turning over in my mind since. “You will see people who you think are stupider than you go much further than you, because they worked harder”.
It’s a convenient way to excuse career stagnation, but I’d like to make an addendum for the modern age: you don’t necessarily have to work harder, you just have to be willing to turn yourself into a shameless self-promoter.
