You need to train your capacity of letting go of ideas, projects, opinions.

Because when you get too attached to those, you risk getting your perspective on the world narrowed. And that’s when you stop learning and developing.

There’s no need to start with big things, but if you can open yourself to a different opinion, delegate a project to somebody you trust, abandon an idea that’s not taking you anywhere, and if you can do it over and over again, that is a great training for your future flexibility.
