How many masters can we possibly serve?

In the Bible it talks about the impossibility of trying to serve two masters at once - God and wealth. I think things are harder now than they were before - we are torn to serve three, four, five, maybe more masters at the same time! It's stressful watching the frenetic pace of people trying to serve God and money. But now it seems we have to serve our jobs as master if we want to keep them in an age when people are getting laid off. We have to serve our homes if we want to keep them from falling a part. The greatest master trying to cajole me into service is my calendar. My life revolves around my calendar, and what it says I need to be doing at any particular moment of the day! If we only had to deal with God and wealth, that would seem like nothing compared to the many masters out there today! But when it comes down to it, money seems to be the one that is hardest to set aside. It's hardest to orient ourselves towards God when the big, flashy gold calf and dollar signs are shining off in our periphery. I know my weakness. That's probably why I choose to have my gifts to the church and other non-profits taken directly out of my bank accounts. If I didn't intentionally offer them as a priority, knowing that no matter what, each month my gifts will go to God through the church, if I waited until the end of the month, I'm pretty sure there would not be much left for God. What do you do to keep other masters from taking the place of God? Any ideas? Insights to share?
