Move to a new city, get a radically different job, get a kid, switch up your routine, pick up unusual hobbies/interests and every year will feel like a new life. Childhood feels very long because you have to go through mandatory checkpoints imposed from the outside, add that to your adult life and it'll feel the same. Why don't you go get a parachute intro course next weekend? Or rent a car on a race track? Go ice climbing next winter? Join a yoga club, a music class, a reading group, a dance class, &c. try things you don't necessarily want to do and you'll open many doors.
Most humans have a tendency to go the path of least resistance, and in today's world of working from home and unlimited screen based entertainment you can very easily waste decades your life
