Learn English – a word for someone who tends not to think too much about life?

word-choice

What is a word for someone who tends not to think too deeply; often about life, themselves or the world (something more neutral than "shallow" or "oblivious")?
Perhaps my difficulty is that i personally don't think that not thinking is a neutral characteristic. Plus, the type of person i am trying to describe does not necessarily take life with ease or serenity. The word i seek is more about thought-life, than temperament. A non-thinking person can still have a negative, angry, unpleasant (etc.) outlook on life, they just don't question it.

I'd say such a person is happy-go-lucky
