Because it's easier...

It's easier to laugh than it is to cry,
that's why I do it.

It's easier to smile than it is to laugh,
that's why I do it.

It's easier to shine than it is to fade,
that's why I do it.

It's easier to fly than it is to crash,
that's why I do it.

It is easier to love than it is to hate,
that's why I do it.

It is easier to forget than it is to remember,
that's why I do it.
