Totally agree. I think when people hear the word "lazy" they think "incompetent", like "they didn't know how to solve the problem, so they took a lazy route by not doing it very well" when this is not what is meant by the phrase at all, it is exactly what you said.
I would also say that it's doubly important with the experience because I've seen people spend far too much time one something that they think will save them time in the future, but that future changes. It's a balancing act.
