I interpreted this song as describing people who don't try at anything. They see no purpose in doing so and wonder why others do.
"Oh my God, I'll probably have to carry this whole load
I couldn't remember if I tried"
This line is describing how overwhelmed these people are when something difficult comes their way; they never tried, thus have no experience, thus can't believe how hard some things in life are.
