I told them to take control of their calendar, and don't let yourself be busy'd out of advancement and growth.
But learning and growth and development -- these take focus, and quiet, and large blocks of unbroken solo time. And for that you have a constituency of one: you.
Nobody but you is looking out for badass future you. Nobody knows all that you juggle when they make a request. It isn't their job. Their job is them; ✨your job is you✨
Be more selfish. Let the world serve *you* sometimes. Tend to your own upper bounds and expand your limits.
You cannot expand and grow while stuck in reactive mode. You must put on your oxygen mask before assisting others (as the saying goes).
In any given case that may be true. In aggregate, though, you can make time or make excuses. And when you make excuses, you are topping out. Right where you are.
Also, I absolutely do go for years without much heads down time, eg as a new manager. To everything there is a season.)
