“That’s just how I am” is sometimes true and sometimes a door you locked from the inside.

Some traits really are yours and not up for negotiation. Others are habits you stopped questioning years ago, and calling them your nature saves you the trouble of changing them. The giveaway is timing: as a fact the sentence sounds plain, and as a defence it arrives fast, usually right after someone asked you for something.

Listen for yourself saying it this week and finish the thought honestly. Ask whether you have ever actually tried the other way or only assumed you could not. Pick one small case and test it once before you decide it is settled.
