its a happy day!! coz god made this day... there's this sunday school song.. not sure if you've heard it before.. it goes something like that

It's a happy day
and I thank God for the weather
It's a happy, happy day
and I'm livin' it for my Lord
It's a happy day
and things are gonna get better
Cause I'm livin' each day with the promises in god's word.

reminds me a lot that.. god made our days... and we should be glad.. and rejoice with the moment.. not sulk when things are down.. for the joy of the lord is my strength.. =)
