How to measure user happiness?

How to measure user happiness? Are a piece of paper and a pen enough to start a UX Designer career? How many colors should we use on the website?

The answer to these and many other questions you can find in probably the most interesting podcast I have recorded so far.

This time I was supposed to talk to Elżbieta Krutysza, who knows UX like no other. Hope, you will like it!

Note: Podcast recorded in polish.
