what are your intentions?

when i was a kid i was taught that when one does a mitzvah lo lishmah bah lishmah. when one does a mitzvah without the proper intention  you will eventually do it with the proper intention.  this is so profound. this means that hashem knows that people aren't always on the level to do the mitzvah totally lishmah and will give us points for a mitzvah even if it is done by rote. this also means that one should not look down on those who are religious but are shomer shabbos more because this is how they are than because they consciously made the decision to become religious. it also invalidates those who  won't do mitzvot because they don't believe in them even if they might get enjoyment  doing them lo lishmah.
a few years ago i went to a book reading that featured  shalom auslander of foreskin's lament fame. at the event he proudly shared that he specifically did not want his wife to light chanukkah candles if  she said any brachos when she lit them or if she assigned any religious meaning to them because he did not believe in any form of religion. he was just so frum about not being frum.
being an observant jew is not for everyone. i get that. i also think that its ok to be an observant jew without  ideologically agreeing with every aspect of the religion. i also think that its better to observe a little of the torah than nothing at all. i do not think that hashem expects everyone to be perfectly observant , i think he just wants us to do as much as we are able to at whatever level we are on.
