Other forms: attainments
The effort put into something and the pay-off when the work is over is called attainment. Attainment of your goal of learning to make the perfect omelet requires breaking a lot of eggs.
An attainment isn't just handed to you — you have to earn it through skill and hard work. In fact, in slang, attainment is used interchangeably with skill. You might say that the inventiveness and originality of a particular rapper is his attainment, just as his fame, fortune, and respect in the hip-hop community is also his attainment.
