I was trying to allude to this a bit, but maybe it didn't come across clearly. I was thinking more about how you approach getting help to achieve a goal. And probably a good way forward is a mixture of occasional 1-on-1 sessions with experts in your chosen activity, followed up with more regular sessions with a general trainer who can help you achieve what the expert says you need to improve. For example, specialist advice can range from very specific technique improvements, to more general comments like "technique is good, but you need better core strength" at which point a personal trainer might be a good call.
