this is gonna sound odd for me.
Being out in nature because I never get out enough.
Overcoming a difficulty though this one is hard to describe in words.
Klonoa games obviously
I like to learn even if it is slow this too makes me happy.
Having my ways of thinking tested. This too is a bit hard to describe in words
Actual real peace. Not that forced fake peace crap but real peace.
Having a deep sleep. Which for me is rare.
I like to build stuff more than I admit. obviously building things makes me happy.
I like "movement / flow" but I can't find a way to properly express this or why it makes me happy or sometimes even what it describes.
Certain art's with a strong lively vividness or expression. I don't know how to express this very well either but certain kinds of art make me happy and it can be as random as a well made tree.
Being able to be my more real self which has been actually very hard to do lately. I'm also trying to fix that now.
I could probably think of more but I'm half asleep atm so I'll leave it at that.
