When energy is a good thing, when energy is a bad thing

Hi,

"Some are energetic [zariz] and are rewarded for it, and some are energetic and lose as a result of it; some are lazy and are rewarded for it, and some are lazy and lose as a result of it.

"'Energetic and rewarded' refers to a person who works all week and so does not need to work on Friday afternoon, close to Shabbat.

"'Energetic and loses' refers to a person who works all week, including Friday afternoon, close to Shabbat.

"'Lazy and rewarded' refers to a person who does not work all week, and does not work on Friday afternoon, close to Shabbat, either [he accomplishes a Mitzvah, even without intending to do so].

"'Lazy and loses' refers to a person who does not work all week, and works on Friday afternoon, close to Shabbat."

(Talmud, Pesachim 50b)

Have a great day,
Mordechai
