Whenever you feel lonely, remember there are people who has no family.
Whenever you throw away your dinner, remember there are people who beg moneys for a bite bread.
Whenever you play with water, remember there are people who walk miles for a bucket of clean water.
Whenever you feel poor, remember there are people who has no home.
Whenever you feel nobody could understand you, remember that they want to be understood too.
Whenever you feel lazy to go to school, remember there are kids who don't have moneys for it.
Whenever you feel you just wanna runaway, remember there are lost people who missed their family.
Whenever you feel you'd rather die, remember there are people who fight their sickness for life.

Just be grateful, and you'll understand.
