how do you know you're indispensable?

Seth Godin's five-star book "Linchpin" give you two choices if you want to be indispensable. The first choice is to take advantage of (leverage?) people who want to be told what to do. And the second choice is to make yourself indispensable to a boss (includes clients) who values you and rewards your work.

We like the second option because it's the human-centric approach. The mindful approach. 

The first option, in our opion, is exploitative.  But we recognize that we do need these options in our day-to-day lives. Just not when it comes to human creativity and innovation.
