The Ship of Theseus is a thought experiment proposed by the Greek philosopher Plutarch in relation to a story about the Greek hero Theseus. If every single piece of Theseus' ship has been replaced gradually over time, is it still the original ship?
You are your own Ship of Theseus, constantly replacing your parts over the years (metaphorically and literally). But concerning yourself with the question of "who you are" at any point in time is inviting an identity struggle that is unnecessary.
The reality: There is no original version. You simply exist. You never become, you are in a constant state of becoming. This means that you simply need to embrace all change and not worry about clinging to some old version that may have existed.
