I go for mine - You don't just want it, you need it, and you're not going to

You don't just want it, you need it, and you're not going to let anyone stand in your way.

I go for mine, and I don't care if it means my friend is sad.

She had the last soda. I go for mine and I took it.

I go for mine, even if it means I get yelled at by my dad.
