Consider asking yourself why you struggle to compromise and what you think it will cost you if you do. There may be some sort of block or narrative running in the back of your mind that is preventing you. You may see compromising as giving in, for example, or you may feel like you are being taken advantage of if you compromise. Ask yourself if your inability to be flexible is based on what's in front of you, or if it is a response that is more tied to an experience you had in your past.
