Wrong.

That's what the media tells you.

That you are small and insignificant but they big and important.

They are wrong.

If it werent for each of us NONE OF THEM would exist.

The high and mighty NEED us to recognize them and give them purpose.

That means you MATTER A LOT.

Without a person who cleans the garbage we would be burried in garbage.

Without people who work at the register at the store no one would be able to buy anything.

Without construction workers no one would have a place to live.

I understand that its hard to make yourself believe that these things matter but it takes practice in positive thinking to accept that.

And stop watching TV is my advice(tv will rot your brain off)

??? That some artists show an imaginary being laughing when bad things happen in NO WAY means that laughing is a bad thing.

You seem completely confused about many things.
