Does Vs Doesn't

It doesn’t matter if you’ve fallen many times
It doesn’t matter if you’ve been cheated
It doesn’t matter if people have gone away
It doesn’t matter if you were defeated

It does matter how you behave under stress
It does matter to pick yourself up after a fall
It does matter you take responsibility
It does matter who stands by you through it all

It doesn’t matter what hurtful words people say
It doesn’t matter if you’ve been lied to
It doesn’t matter if things change
It doesn’t matter if the world doesn’t revolve around you

It does matter how you handle situations
It does matter to enjoy joyful things
It does matter to be more careful
It does matter to focus on what happiness brings
