The world seems to be imperfect
It is because many people are ignorant and they make “bad” choices in life.

Many people choose to attach to lower emotions like hatred, greed and sadness.
Not many people choose to embrace higher emotions like love, compassion and gratitude consistently.

To help in improving humanity,
the best thing you can do is being a good example.

Practise what you preach,
choose to think wisely
choose to feel positively
choose to talk and act properly
and choose to treat others well.

Let go of attachment towards negativity and avoid things that are unhealthy

By being a “good” person,
you are changing the world starting from yourself.
People around you are connected to you so it is important to show them good examples of livelihood.
The reality will gradually improve.

It won’t help to attack negativity with negativity because negativity will bring more damage.
Choosing positively is the healthy way to improve situations.

To help humanity,
The best thing you can do is being a good example. :)
