Be as careful with a minor mitzva as with a major one, for you do not know the rewards ...Pirke Avot
When we are trying to do Hashem's will it is easy to get so involved with the Major Mitzvas that we forget the minor ones. Of course kashrut and Shabbos are important, but that does not mean that we can forget other mitzvas.
In Oa we have to follow every part of the program. We can't say, I'll weigh and measure my food, but I don't want to go to meetings, or make phone calls. We do not know what part of the program is going to bring us health.
