Way more often as not, you can read me answering this question as “no, if you do not enjoy the process, you likely will not succeed.”
But is this “attitude” fixed or can it change?
This is a good question and it does apply to archers. This is especially the case in that young archers often “succeed” at winning championships without practicing. These are archers who go to, say, a weekly JOAD session, which is as much social as it is instructive, and then attend competitions and win them. This can go on all the way up to state and national championships. This is a manifestation of a lack of competition. These kids do win without practicing because they can win without practicing. If more kids were practicing effectively, this would not be the case.
Since it is the case that some kids do win without practicing, they logically think that practicing, or practicing a particular way, is unnecessary. Of course, if they continue on, they will reach a point where they no longer win, and many of these kids drop out at this point, either because they have a fixed mindset and think their talent ran out, of they just didn’t want to have to work at the sport.
For the number who hit a wall and ask for help, there may be an answer: some people feel that you can trick yourself into enjoying boring subjects, like archery practice. This is a bit like neurolinguistic programming I guess, but all you have to do is get them to tell themselves that they like learning about archery. That they find it interesting. That they want to know more. Even remote curiosities about a subject, like searching online for “What are archery bowstrings made of?” should be encouraged.
Learning that they can “reframe” their own attitudes is a way to motivate them to go deeper into any subject. Even if the task or subject is boring, even if it is not something they would choose to do, this is a valuable tool which will also pay dividends later in life.
Of course, as a coach, making practice boring is not a plus; making it interesting and challenging is.
