Style is preference repeated until it becomes identity.

Do the same thing enough times and it stops being a choice and starts being a description of you. The way you dress, the way you write, what you always order. None of it was decided in a moment; it accumulated until people could recognize you by it.

That means your identity is being built by your repetitions right now, whether or not you are choosing them. Look at what you do by default. Some of it is worth keeping on purpose and some of it you would not choose if you noticed you were choosing.
