Learning is not only about books and lectures. It is new skills, new hobbies, the ability to adapt and develop. Every time we discover something new, we grow, become more interesting to ourselves and others.
Plus, learning develops the brain, improves memory, and often social skills: new acquaintances, communication with different people, exchange of ideas. And yes, sometimes learning can be funny or absurd, but this is where the joy lies - because mistakes are inevitable, and laughter makes the process easy and exciting.
And most importantly: it is never too late to try, start from scratch and be surprised at your own capabilities. The world is huge, and every day can be a lesson.
