Janet Fitch said this quote

Who am I? I am who I say I am and tomorrow someone else entirely. You are too nostalgic, you want memory to secure you, console you. The past is a bore. What matters is only oneself and what one creates from what one has learned. Imagination uses what it needs and discards the rest— where you want to erect a museum. Don't hoard the past, Astrid. Don't cherish anything. Burn it. The artist is the phoenix who burns to emerge.
