Agile suggest that teams should fail-fast to enable quick learning from mistakes. Learning from failure is one approach, you can also learn early and fast from successes, by doing experimentation, or by using a plan for knowledge acquisition.
Working in an agile team can sometimes be stressful, when the needs of the customers are unclear, if there is a lot of work to be done, or when team members are having difficulties doing their work.

Scott Ambler published the results of his annual IT project success survey, in which he examined the impact of methodology on project outcome. He looked at five different "development paradigms" and how they influence project outcome: ad-hoc, iterative, traditional/waterfall, agile and lean. Ambler's definition of success is deliberately subjective - how did the customer feel about the outcome?
