Since everyone enjoys a good list:
1. Family - Spending quality time with family is more important than writing (though writing may lead to having more time to spend with them).
2. Friends - Friends are a bit of a double-edged sword, but a friend in need or whom you haven't seen in a while is definitely more important than writing.
3. Charity - Giving of your time and money to those less fortunate than you is more important than writing.
4. Your Health - Keeping yourself healthy and fit is more important than writing.
5. Your Job - Is slightly more important than writing until your full time job is writing.
