I had an idea, which helped me to fight with my tilt issues and I thought
I could spare it with you. Maybe you will have something to add as well. 
Poker community often times try to think as being in 10% of the top in
stakes they are playing. That's called egoism and we all have it no matter,
what we say, because "we are", "we exist".
We call others fish, donkey, whale, idiot, bad player, etc. To add to this,
we also mark players on our tables with some kind of color, which screams ... FISH.
Then comes the interesting part, where we might just let our feelings take
control over our game. For me it's like, I know he is "that purple colored
player", he is so bad and that adds so badly into coloring too many
people whit that color. Without many reads, etc.
So, the way it started to help me was to admit, that I'm a bad player
as well, but I do have different leaks. We all have dirty spots in our
game and the guy on our right has them as well. The trick is to know
both, where do we both play badly.
Now, whenever I see a player, who has some significant leaks,
he is just a player, who need a serious work on his game. That's it!
For me, fish swim in the ocean, however there are bad players at poker
tables, who need to improve.
This is all based on my own experience. If you have something to add, please.
Have fun at the tables!
