On the other hand building a skillset is not necessarily what people think. It's also what you gain when you're not paying attention to "building a skillset" or making it big.

For example I have met few good software engineers that are also good at design or marketing - but those few rare gems out there are fuckin' awesome individuals.

    sure as hell don't rest on your laurels

IMHO, some rest is precisely what many of us need.
