What is important?

I have come to realize that the things people tell you are important are often not very important at all, while other things that most people pay no mind to are actually very important. 
According to everyone at work, the most important thing in the world is for us to meet a deadline for getting a report completed.  They say we HAVE TO meet the deadline.  We CAN'T miss it.  Therefore, they are working day and night, taking their work home with them to work on it at night and on the weekends.  They are giving up everything else in their lives for the sake of this goal.  They expect me to do the same.  After all, it is IMPORTANT, or so they say.  But is it?
What happens if we miss this deadline?  I'll tell you.  We will get a slap on the wrist.  Some people might say bad things about us.  My supervisor might get a blemish on her record.  That blemish might make her a bit less likely to get a promotion.  That is what they are concerned about--doing a good job so that they look good, can get a promotion, and make more money.  Is that the most important thing in life?  I think not.
What is important?  I've decided it is this.  Doing what we can to save lives, help people, and to alleviate suffering.  That is what is important.  Taking care of our friends of family.  That is what is important.
I will not work overtime to meet some meaningless deadline.  It is not important.  I have othr things to tend to that are more important than that.  They can do what they want.  I will not play that game.
