What you ask of the world you must ask of yourself, or it would not equate. Are you peaceful? Do you feel a sense of inner harmony, equilibrium, Balance? Do you experience inner and abiding joy?
If you experience those things, then your expectations are practical and realistic, but if not, why should you expect it of others?
Is there no hope? Then should I ask, are you optimistic? 'cause if you're not, you are already in a self-defeatist zone.
The ancient message of 'man know thyself' is very real, and loving oneself is also very real. Work on the inner mirror, remove the stains, and the clearer the picture, the greater will be your capacity to answer your own question.
Perhaps you're already doing this right? If so, I do not know that the question will arise. But hey, that's just my response after 32 years of prayer, interior work and service to mankind. I may be wrong. Much peace.
