으면서 살다

live your life doing something

"-(으)면서" (while) plus 살다 "live" — how you go through life, not what you happen to be doing right now. Every line here is about a way of living: let's help each other out, live with a reasonable amount of stress, live finding happiness in it, live off memories like these, lived through a lot of failures. It is the shape advice comes in — 도우면서 살아라, "live helping others". Note that one example line is printed twice in this list.
