Hey Akash how are you doing today?
Akash when you go the gym after a long break, you don't feel intimidated or overwhelmed by the work even though the amount of work you and beginner is going to do is similar (similar weights, similar exercises). So what's the difference? It's the knowledge and experience you've gained over the years. You know the terrain, you know the drill, you know what needs to be done and you're not afraid to experiment and start working.
Same thing applies to failure. You think you're afraid to fail but you're never actually starting from scratch. You always start with all the experience and knowledge you gained along the way.
Have a lovely day my friend
Akash
