when you learn that you're not entitled to anything in life, you become thankful. When you expect nothing, your happier when you get something, and a lot more thankful too.
I live this way in real life, with no preset conceptions of entitlement. It's very austere, but it also teaches self-reliance and appreciation. You aren't angered or disappointed when you don't get something you want from other people or circumstances; on the contrary, it's far easier to realize that wanting it does not entitle you to it, and thus you haven't been deprived of anything unfairly. It would be nifty if everyone adopted this style of thought for a day or two.
As to the question, I am personally negative. Thoughts, expectations, behaviors... they all are founded on pessimistic principles. See above.
In regards to evaluating external situations, however, I am neutral. I'll observe and infer both positive possibilities and negatives ones.
Next, when it comes to other people, I try to be positive - as in, I'll often give someone the benefit of the doubt, or I'll encourage the better side of a person regardless of their negative traits.
Finally, I used to make people happy without cease. Outward optimism, constant complimentation, cheerful attitude, so on and so forth, Gave me a bit of a reputation here. Somewhere along the way, though, I stopped caring as much as I used to. Now, more often than not, I am ruefully sardonic and insensitive, though sometimes facetiously so.
Wordiness. Or: prolixity. Ho hum.
