Uh, a bad experience is a waste of time.

And I'd call these opinions, not ideas.

Not sure if I agree with being downvoted but out of my hands. :)

You're being downvoted because you said flying is a waste of time, which is banal to the point of trolling.

It's not a waste of time if it gets you where you want/need to go.
