For me I learnt the most in my first year of working. It was also fast paced.
My learning continued in my early career. However it was lesser. Both speed of learning & amount of learning slowed down.
By mid career my learning slowed down. Both pace of learning & amount of learning reduced.
By late career I had my maximum learning. I started to learn like I did in my first year. Both speed of learning & amount of learning were far more than in my first year. This helped me completely change tracks & reinvent my career.
Learning is a choice, it is not dependent on the years of experience but our desire to learn & grow.
