To base success on either struggle or accomplishment is misguided. Success is uniquely defined by each of us, and it is impossible to base that definition on short term goals rather than values. Both struggle and accomplishment are fleeting; success, on the other hand, is the ability to reach satisfaction when floating somewhere between the two.
To illustrate the idea of either struggle or accomplishment leading to a feeling of success, we can look at a baby taking its first steps. A baby spends months developing the skills that allow it to walk. First, it must crawl, then it must stand, and eventually it begins to take its first steps. Admittedly, the child feels 'successful' when it takes its initial steps. This is because it was forced to struggle, leading it to believe that it has accomplished something.
However, over time, the child loses that feeling of accomplishment and moves on to other objectives, such as talking or improving its motor skills. The feeling of success, therefore, has disappeared, because it was based on short term goals.
On the flip side, if one bases success on values, they begin to develop a life that they are satisfied with. They are happy when in the midst of struggle and accomplishment, because they have worked to achieve the things that are important to them.
