The point at which you decide to tidy the beach doesn't really determine your success or failure in having builders when you need them. Delaying that task is a choice that I make out of practicality. You don't
need to do it any earlier and your villagers aren't distracted by the new leisure opportunities available to them!

There are certainly other successful ways to produce the talent you need when you need it.
There are actually many ways to play the game and many paths to the end. For example, I've solved the last puzzle after puzzle 2 and "finished" the game with no dead villagers. I say "finished" because there's one puzzle you can't solve until you have at least one villager die!

The difficulties in training master builders will be corrected in the v1.1 update when it's released.
