To me happiness is when I can create smiles on my family's and buddies' face for the things I do.
Happiness to me is when my family smile for the things I have for them proud to of.
Happiness to me is when my buddies smile for the little help I do for them.
To sacrifice or to hurt myself, it sounds stupid.But if it can make them smile, I will because at least when I'm old enough and about to die,I will never regret the life I had.I have made my loved ones smile.
