I'm unsure if you are asking for advice on how to improve because your current manager marked you as inconsistent or if you think GP is calling all people "who are trying to improve as inconsistent"

I'm a manager. I want to improve ALL of my team. To rephrase, I want each of my members to work on things that benefit themselves (they improve) and benefit the team - if we can't do that, I zoom out: how can they benefit the team, department, the company, the industry, the world. You might notice this means I may find a better place for them on a different team or even outside the company. All of this. ALL OF THIS is trying to help the person in an area that he/she wants to grow in.

Growth opportunities are very diverse: coding a new language, learning at a seminar, teaching at a seminar, side projects, art, games, mentorship
