There is nothing good or bad for being substantial and heavy. Having milk in a coffee just makes the bitterness in my coffee less bitter. 

There is nothing good or bad for being bitter either.

Isn't it?

I hope this opinion is not going to make me a contrarian.

He is just like milk.

I know it with all my bitter soul and pessimistic brain that he is good for me. He is full of inspiring nutrients and alleviate the pain. Sometimes I just don't like my life to have too much happiness. 

Happiness is too substantial, too heavy. I'm not used to living a life without bitterness. Happiness is not my comfort zone.

A cliché quote that can be found on many of basic-hopefully-meaningful posts says "Life begins out of comfort zone." But how should I deal with wanting to be alive is out of my comfort zone.

Being weird and crazy is qualitative. You can't give me a scale of 1 to 10 to say it's not good for me by ranking 1 = bad and 10 = good.

You should be a math teacher if you want to do some calculation and grading.
