In every thing give thanks: for this is the will of God in Christ Jesus concerning you. - 1 Thessalonians 5:18
In Luke 17 there were 10 lepers healed by Jesus Christ but only one came back to give thanks.
Gratitude is a wonderful thing, I bet everybody likes receiving words or deeds of appreciation, more so God Himself who though we don't usually acknowledge has already done so much for us. When some things are going bad there's always the small stuff to be thankful for, it may be good health, family, friends a job etc. Not that we should be complacent where we are but when yo look at it there's always something to be thankful for- it's never really that bad.
So every once in a while take some time to say thanks and appreciate God and the people around you!
