When you tell your self its a "good day today" even if it is rainy and cloudy day, and think were is the "good" in that. Then try to think again..."ok there is clouds and it possible will rain..but does that matter when i have roof above my head or money for food or ect"
It is the littel "things" you have that others dont have you must focus on.
Not because that others dont have roof above ther head or money too buy food for but i was trying to make you understand the idea or concept
Just an advise from me.
