Which constellation has the most positive attitude towards life and no sense of crisis?

I think Aries people have the most positive attitude towards life. They usually say that they have no sense of crisis.

I have a roommate. She is an Aries. I think she is the most optimistic person in our dormitory. Laughing every day, never seeing her cry or complaining about anything. I asked her curiously, does she really think life is wonderful? Why else would you be so optimistic?

She told me that she thought life was beautiful. Although many people tell her that life is not good, she thinks it is because everyone's life and mentality are different. She thinks that as long as she sleeps well and watches TV every day, then she feels that life is beautiful. Actually, I like her like this. This attitude towards life is the most positive. In this way, she can always feel the little happiness in life.

But sometimes it is too easy to satisfy, which will make her feel no sense of crisis. My classmates are immersed in this little sense of happiness all day and have no plans for the future. That is, I can live one day at a time, which I think is really bad. People still have a sense of crisis.
