Used to be, now I don't care tbh.

Friendly hasn't gotten me too much good. Maybe it saved myself at some point, but other than that, nah.
I like people and equally don't like certain behavior.

I often gave people the benefit of the doubt. I wasn't naive, just a bit more open-minded.
At one point, I used to think, "If he/she can do it, so can I!" 

Self mastery, staying in my own lane, minding my own business, not hating on anyone.
I'd assume this to be a commonality amongst us as humans on this plane, but it seems not.

For me, this reigns true:
"They hate to see you winning."

Why?

1. They're not (oh well, who cares.)
2. They feel less superior. Friend wishes you well, but only well enough to not be doing better or being
   perceived as doing better.
3. scha·den·freu·de - pleasure derived by someone from another person's misfortune. 
   /ˈSHädənˌfroidə/ I had no idea this was a thing.

Just venting.
