Interesting points from thechak and Mitchel about positivity and realism. I honestly think I am both realistic and positive. And I do like positive people, as in people who accept the bad things but have a good attitude. Sometimes you can't change crap that happens to you, but you CAN change your reaction to it. being positive does not mean being naïve or unrealistic.
Example: you have an accident and end up in a wheelchair.
Kind of reactions:
1. Negative and unrealistic: "this is shit, my life is over, I would be better dead, I will never ever be happy. I hate the driver who caused this to me forever and ever, I wish he dies a terrible death". I could never be with a person whose reactions were like these.
2. Negative and realistic: "This is shit. This will turn my life upside-down, and I don't think I can bear it. Why did this have to happen to me?"... then anger, depression and long-term bitterness. It is realistic, but I couldn't handle a person like this either (note: depression and despair in the beginning are natural reactions... I am referring to long-term reactions here).
3. Positive and unrealistic: "I am in a wheelchair now, and doctors say I will never walk, but I know they are wrong: whatever happens, I know I will walk again and life will be wonderful". Well, I understand why you guys don't find this reaction attractive

.
4. Positive and realistic: "These are going to be hard times, but I am strong and in the end I will cope. My life will indeed change, but I will find new things to do and new interest to adapt to my new circumstances." This is more like me and like the kind of people I am attracted to.
