My Job

I have decided that I really love my job. I work for SIM, a Christian missionary society. My job is to promote missions amongst young people and young adults in Perth. I was trying to work out why I love it so much. Is it because I get to work from home and my own hours? Is it because I get to communicate with so many interesting people both in Australia and overseas? Or is it because I feel that my job is worthwhile and that I know the end goal? Probably the latter (but working from home is a bonus).
