I’ve always believed in the quiet magic of wishes — the kind whispered before blowing out candles or written in the corners of journals. Growing up, I found comfort in words and wonder in small rituals of hope. That love for meaningful expression led me to write and share messages that help others celebrate, heal, and dream. When I’m not crafting wishes, I’m sipping tea by a sunny window or finding beauty in the little things life offers.
