Who are the people who want more abilities, skills, improvements and/or experiences?

Those are the people whose passion is learning. They are openly and actively looking for all four of the things you mentioned. You never have to force them to learn. They love it.

They do not limit themselves to institutionalized environments, or to any particular instructor.

They call upon every ability, skill, improvement, and experience that they've had. Because they do this, they constantly sharpen ability, refine skills, improve everything and experience it all in full. They never stop learning.

Find the dedicated learners and you'll have found the people who want those things. You'll find more than you ever dreamed as well. Enjoy the pursuit. I can assure that passionate learners always do.

Thank you for the A2A. I appreciate being asked.
