How does the shown object point to a better world?

On a bicycle tour in spring I saw this graf­fiti under a bridge — and it’s so right:

Make some­thing out of your life that is worth being told (gladly).

This is how I imagine a better world:

Life is an end­less story. Every chapter in itself is an excit­ing nov­el. Wheth­er good or bad, bet­ter or worse, can only ever be judged from one angle and nev­er abso­lutely. So a bet­ter world is just as unthink­able as a good world. At best, a world in which every­one feels at home and com­fort­able is desir­able. My own life with all its high ups and all its low downs is already like that — I have been giv­en a lot and I can only be grate­ful for it.
