The single greatest cause of happiness is gratitude.

I am grateful to the Lord for granting me just what I needed.

A life is not a waste of time.

Saying 'thank you' signifies sense of gratitude, but it also implies your incapability.

The priceless gifts (life, love, joy, goodness, family, nature) are freely given by the Creator.

Be not wishing and pining but thankfully content.  For it is a short bridge between wanting and regret.'- from 'Dimpellumpzki.

O Lord, be magnified for your wondrous works.

Best friends are treasures. Hug them for their caring. Applaud their accomplishments. Laugh with them gratefully.

I can and will improve the world.I will smile, show kindness, and be grateful.I refuse to be unhappy.

Gratitude doesn't change the scenery.  It merely washes clean the glass you look through so you can clearly see the colors.
