In every one of your childhood delights, there was God, teaching you about himself. And the more we can reach into this deep well of delight, the more we can give to others. Not only do our childhood hobbies and dreams bring us joy, they often involve BIG visions of how we can help others, too. Like the Japanese principle of ikigai, your childhood dreams can be the key to not just what you love, what you are good at, and what you can be paid for–but what the world needs, too.
So, reignite those dreams! Get out that journal, be brave and record yourself singing, if only for yourself. Buy that Lego set so you can feel what it's like to build again. Start with doing what you love without judgment, and the rest will follow. Your inner child will thank you for it, and so will your future self!
