Dig out the thing you were obsessed with at twelve. Do it once.

The sketchbook, the cassette, the chess set, the keyboard with the demo button — somewhere the actual object still exists: a box under a bed, the cupboard at your parents' place, the top shelf that needs a chair. Dig it out. If it's genuinely gone, the nearest secondhand shop sells a cheap stand-in for the price of a coffee. Then one full go, today — one page drawn, one piece played through, one routine front to back, one chapter aloud. Twelve-year-old you left things in that object — a name in marker, a dried-out pen, a margin note — and there's no knowing what until it's open in your hands.
