Knowledge builds up when you live through things - watching them happen or being part of them yourself. What counts isn't just big moments; even small ones add up over time. These situations stick with you, changing how you see stuff, what you believe, and who you become. Learning by doing hits different compared to reading or hearing about it - it’s more real. That kind of knowing helps shape choices later on. It pushes you forward in ways books can’t match.
Nothing can substitute it.
