You set the standard.
You decide how good something ought to be.
You decide which direction you want to go in.
You decide what is right for your life.
You decide what you will or will not accept in a relationship.
You decide what salary makes you comfortable.
You decide how much privacy you ought to have.
You define your boundaries.
You set the standard for what is good and acceptable and right in your life.
No one else.
