Most people get confused with achieving high performance. It can be a complex animal and has the ability to create doubt when cause and effect takes place. One thing is improved and it can cause a problem elsewhere. You might increase volume but that means you’ll be more tired. It will mean you need more food. It will mean you wont have the ability to do the race intensity sessions with the same intent.
You might focus on technique but that means you have less time for volume. It will mean you have to commit fully to a review and reflect process, thus meaning less time for other things.
There isn’t a secret formula for handling this complexity. It’s hard, but when it’s hard you need support. You need direction. You need coaching. That’s what makes it less complex and overwhelming.
