There is so much beauty in the world, and the more we focus on that the more energy we will have to create great things, etc.
Life can be tough for everybody, so there is no need to make it tougher by being negative because it won't change anything!
Some people are addicted to negativity, and you can't help them unless they change their perspective.
They feel safe in their misery, but it's just because they are afraid.
We can all have a bad day and be negative, but people who are addicted to negativity are negative more or less all the time.
It's a slow kind of suicide, just like any other addiction.
By the way, if people attack you because you are happy then it's because they are jealous of you!
