We are all replaceable, but not unrepeatable, that's the difference " it is like:
There are no unreachable goals, only people who give up half way,
that's why sometimes I think that we should not take things so seriously, everyone carries a suitcase of various things (doubts, complexes, attitudes, gossip, criticism and absurd and negative points etc.) no one dies from this, but if by stress.
I have noticed in this year that many talk about Peace, in all senses, but nobody is educated for peace,
Everyone is educated for competition and this is the beginning of any war (many are filled with envy, selfishness, personalism, greed, etc).
When we are educated to cooperate, help and be in solidarity with each other, that day we will be educating for peace.
