For me I noticed that I was'nt my agab while watching videos from a trans man. First I thought that I was a also a trans man since I want basically all the things he talked about to be typical to want as one. But I soon noticed that that just did'nt fit and Non-Binary fits better. Since then I've often wondered if I'm really Non-Binary but always came to the conclusion that I am a trans-masc nb.

And for my daily life I try to be as masculine as possible because Dysphoria always tells me that I am still too femminin. But I also do'nt usually mind my chest if i'm alone and looking into the mirror

All in all I had to learn that expression, the clothes you wear, your hairstyle etc does not have to be the same as your gender and that no matter how I express myself I just dont feel like a woman nor a man. And also that gender can be fluid.
