Convert problems to challenges

We had sprint planning meeting and it was really hard meeting. Lot of unknown things about stories and problems were there and there and it seemed that all this product is one big problem. So what our product owner suggested, was like this (credit goes to Charlotte Way):

Let's change the word problem to challenge and when you have a problem, instead of saying I have a problem, say I have a challenge.

And you know it really works. It was not so depressive anymore to talk about those problems, because there were no problems! Product now is a challenge and bad 3rd party API is a challenge, that bug is a challenge and when you get used to that word it really works, and everything looks much easier.

So from that day, I do not have any more problems, there are only challenges!
