Indeed. There are studies about grit and determination over time being strong indicators for possible later success. In any endeavour having some unknown value, overlooked by others, there will be periods where you feel all alone, experience some disinterest or need to grit through some necessary activities/work in order to push forward. There will not always be happy feelings about what you do or even why you do it, though such feelings will be more on the level of superficial aversion and procrastination. In activities and studies with heavy competition, that competition will be extremely hard to beat. Both may be overcome by grit and determination, while those with natural abilities or superior training, often give up earlier due to various unrelated reasons.
