”樂在其中”的英文是什麼?

我想知道"樂在其中"的英文是什麼,
Found happiness within.
John had a bad fall in the ball game, but he found happiness within.
Amazon forest is hot and humid, yet the adventurers found happiness within.

"Have joy in it" or "enjoy oneself in it".

e.g.
Though cooking is difficult, my wife seems to have joy in it.
or
Though cooking is difficult, my wife seems to enjoy herself in it.

without context, it's hard to tell, so, can you quote the conext as well?
which means give me the whole sentence or related paragraph.
