We have 4 kids, and in order to keep Christmas manageable and fair we get the kids something from each line of this rhyme:
Something you want, something you need;
Something you wear, something you read.
We spoil the kids a little more on their birthdays, because their birthday is "all about them". Christmas is about others and giving.. so we just trying to keep it simple.
Hope this might be helpful (even though it didn't really give you any specific ideas for a 14 year old boy!!LOL)
