Honestly.. I think not.

There are things that I could change, if given this opportunity - like my poor eyesight, maybe make myself a little bit taller.. But I feel like all of these things, positive and negative, have lead to where/who I am today. My poor eyesight forced me to adapt in the sporting environments I'm so often in, making me a far better athlete than I would have been without it (I think), and so on.

And I'm really happy with who I am and who I'm working on becoming.

Everything I don't like about myself is something I can actually work on, and I'm really appreciative of that fact. Not everyone is as lucky as me.

Great question btw!

Edit: Also, after reading further, I also agree with the other poster about "self" more being who you are at the time. I would say we're always changing and the person you were a year ago is vastly different to the you of today, but you're still undoubtedly "you".
