What is some advice to climb the corporate ladder quickly in this world?

I’ve spent 30+ years in boardrooms, watching hundreds of people rise and many fall.
The truth is that the fastest climbers are rarely the smartest or the busiest.

They follow a few unwritten rules most people ignore.

Here are the 5 rules I’ve learned about climbing the corporate ladder faster:

1. Stop chasing only “hard work.”
Hard work gets you noticed, but only to a point.
I’ve seen brilliant employees buried in tasks while others with half the workload leap ahead,
because they worked on visibility, not just effort.
