My personal chellenge
I had to think up 10 hypotheses a week, 3 of which must be powerful and potent. Hypotheses must be directed to increase of ARPU and accesses. At the same time I designed and implemented about 5 A/B tests a week.

As Ultimate Guitar had no UX research culture and no goal to build it, I had to find various sources of knowledge to be successful.

Are you really creative?
The first few months of work were in Hard Core mode. I tried and was wrong all the time. I made up a lot of ideas, but they were either not strong or they didn't give me any growth, although they seemed logical and convenient.

At that moment I thought about what means to be creative indeed. If you work as a designer then you are already creative by default. But I was wrong.

I felt pain and suffering as I couldn't make up great ideas. After first months I understood that creativity is stand-alone skill. Real creativity requires constant focus on improvement and maintenance of skill.

I have studied a lot of literature, articles and videos. I consider the following two links to be the most helpful. They were the ones who helped me the most.
