But this is about habits. Proper warm up, proper technique, proper nutrition and pre and post match preparation. I do not think 14 is too early to start preparing properly for a tournament.
I read an article about how Uncle Toni used to argue with a young Nadal about eating properly. He told of a big match before which Rafa ate a bunch of junk food and Uncle Tony didn't say a word. The match went the distance and Rafa ran out of gas and actually wound up feeling sick. He told the story in reference to how Rafa gained his discipline with off-court preparation.
