LIFE

Life
what's that?
life can be explain by maths
like tis equation(1+1=2)
it's constant
but..
sometimes we can change our life but sometimes we can't
life is also like our sky
sometimes blue sometimes grey
life can be divided into three parts:
1. meaningless
2. meaningfull
3. meaningfull+meaningless(50%+50%)

SO....
what's yours?
