Challenge Accepted The challenge for today is to the point. (But it doesn't mean it is easy!)
I don't think keeping a positive attitude means ignoring problems. It doesn't mean you have to bypass your actual feelings. It does mean, though, that you make a decision to look for the positive.
I also think it means that you make up your mind how you are going to interact with the world. You can still have layered, complex feelings about the reality of a situation. But, the only things we can really control in life are our responses and attitude. That's about it. So, deciding to put forth the positive can just be that - a decision.
