Distrust brings frustration and fear. So therefore, the lonely feeling automatically come. So, lonely feeling is not creation of environment, but creation of your own mental attitude.
I think mischievous people always there, ... Some kind of perfect world, that is impossible. Accept that reality. (For) those people who have genuine concern about humanity, make some effort-better than none.
The first beneficiary of compassion is always oneself. When compassion, or warmheartedness, arises in us and our focus shifts away from our own narrow self-interest, it is as if we open an inner door. It reduces fear, boosts confidence and brings us inner strength. By reducing distrust, it opens us to others and brings us a sense of connection to others, and sense of purpose and meaning in life.
