There is a cultural tradition that one is not to seek for a specific calling in the LDS Church.  Did you know, however, that one can ask to become a temple worker?  I learned this when I was talking to some temple workers who had requested to be temple workers.  Generally, the way it works is that either you and/or the bishop make a recommendation to become a temple worker.  It gets approved by the stake president, then the temple president, then the bishop has to approve it a second time.  Sometimes it takes a few months for the whole process to be completed.  Women with young children are discouraged from serving in the temple, but nearly all others are encouraged.   This article from LDS Living talks about Insights from a Temple Worker.  Why do you think seeking for callings is discouraged?  Were you aware seeking to become a temple worker is encouraged?
