Learning to laugh at yourself! One way I bring humor into my daily life is......
I try and keep in mind everytging that happened that was good that day. Even if it was small. It works sorta like momentary happiness
By my sarcasm! 
With good memes.
Interpretive dancing. Anytime, anywhere.
Making puns
Funny YouTube videos!!
memes, tumblr, Bo Burnham
I just start talking about dumb things to my dogs. It‘s random but that‘s probably the reason why it makes me laugh.
Only observing and playing with my pet cat..adds a looot of fun and humor in my life :)
I know that while unhealthy, I use self deprication as humor. I don't always find it funny. rarely will others find it actually.
Sometimes I will use random facts in relation to the topic of conversation, or reference music/tv
Now, I don't tend to use humour because it seems to disrupt all that is around me.
@Duckboy i do that too!
