you are an amalgamation
“I cannot remember the books I’ve read any more than the meals I have eaten; even so, they have made me.” —Ralph Waldo Emerson
In the same way, you are an amalgamation of your memories, of the people you’ve met, of the things you have done.
Even your brain is split into different lobes, all of which handle different things and have “different personalities” (https://www.youtube.com/watch?v=wfYbgdo8e-8)
