Laziness quite often means efficiency and when you combine laziness with a strong drive you end up with the desire to find the most efficient solution possible.

– By Scott H. Young (The Laziest Solution Possible)

I think one needs to differentiate between two types of laziness:

1. Lack of motivation That's the "bad one" – it mean that the affected person should probably find an occupation in a different area, where they can follow their passion.
2. Endeavour to solve problems efficiently That's the "good one" – it leads to pragmatic solutions, or in some cases, the insight that the problem doesn't even exist, or has already been solved.
