play by (one's) own rules
To adhere to or follow only the guidelines or conditions set by oneself, rather than those imposed by someone else. If you want to write for this paper, kid, you work for me, so you can't just play by your own rules! I love working in advertising, but I hated playing by such a large corporation's rules, so I broke off and set up my own company.
