Can this be done mid season, just before the championship?

Mid season, yes. Just before it, we have to be honest.

If there are still weeks between the first conversation and the start, there is work to be done: on the competition routine, on handling expectation, on the plan for the bad day. If it is only days, nothing can be built. Mental abilities come from repetition, not from insight, and that needs time on the water. Anyone promising you otherwise shortly before the start is selling you hocus-pocus.

We can still talk, and it is still worth it. We sort out what is sensible in the last few days and what you would do better to leave alone. And then we take this competition as the occasion to build it properly for the next ones.
