What you say is very true, except when your team is a bunch of people who positively don't want to grow, they just want the paycheck and the minimum trouble possible. You're basically managing to make sure the comfort zone doesn't grow. And that's as tough as it is boring.
I have nothing against the comfort zone, that's perfectly human. But not every team member want to grow.
(me realizes that maybe I has a cultural issue with the company :-))
What I can offer for those who aren't motivated are a few things.
1. It starts at the top. If you make yourself the top then it starts with you and you get to set the tone. A crappy boss can make a great job terrible. A great boss can make a crappy job manageable with some moments of happiness.
2. Find what drives them. Few people are okay with the status quo. This requires building trust with your people and regular communication. If you can find out what makes someone want to do more and grow you're golden.
3. If your job has growth and people just don't want it, find better people. Jobs like this typically have high attrition unless it's something like government, military, or some other rigidly structured role. If that's the case and you want more, look elsewhere. There's almost always someone willing to pay more for someone who multiplies their team's output.
Whatever your journey, I really do wish you a fulfilling and enjoyable life. A lot of times things, especially now, can seem fatalistic or just downright bad. A single candle in the dark can light the way for many others. :)
