Doing What Others Won’t Do
This is the first part about ambition and hard work. If you want things in life (and this applies to way more than just careers) you need to be willing to work harder than the average person.
Doing What Others Can’t Do
The other part is about taking advantage of the opportunities that are exclusive to you. When you do this, you form a career path that is extremely hard to replicate, and as a result, making it easier to secure larger amounts of career capital for the same amount of effort.
