I like this one, from a comment by sundew2008:

7. Friends !

I could not agree more... where would i be now without my buddies??

Quoting Sundew2008:

i smile ,that's because i have a lots of good friends. and i believe that friends always help u in your lifetime whenever u are hapy or depressed . it is truely that they say ,whatever troubles you are in ,you can come to me as we are best friend.
so friendship is valueable.
