Depending on what you want, what you can do, and from a certain perspective, any job is a "waste of time". For one thing, you will almost certainly spend the majority of your time working on someone else's grand idea. (By necessity, most of the people working at Google are doing the same kind of things that everyone is doing everywhere. The environment may be better, but it's the same stuff.)

As one of my favorite supervisors said, repeatedly, "It's not supposed to be fun. That's why they call it a 'job'. Now get back to work."

If you were luckier than others it doesn't necesserily make you an example to be followed.
