Summary: Previous research suggests that everyone who achieves their goals ends up equally happy, but this study suggests that people who set (and achieve) ambitious goals have a greater level of satisfaction compared to those who set conservative goals.
That's my own summary. It sounds patently obvious, and I'm surprised that previous research indicated that people would have equal satisfaction for goals of various difficulty.
