> It's easy to attribute luck or privilege, but perseverance is a crucial factor in most success.

You need luck, or privilege, for your perseverance to bear fruit.

You need both! I'm stunned by how many people cannot grasp this simple concept. Typically, people who have luck tend not to notice it, and attribute everything to their merit. At the opposite, people who didn't get their fair share of luck, tend to ignore the effort part and paint all successful people as lucky slackers.
