To encourage someone to improve, let’s ask for their help.
First, we make it clear why it’s important to us. Next, we acknowledge how difficult the current situation must be for them. (Example: “It’s gotta be stressful to deal with all the blowback when you miss a deadline.”) Then we help them explore why they–for strictly their own reasons–might want to change. Once they are on board, we can talk about how they might go about improving and how we might help.
Far better than hoping, ignoring, and demanding, ya?
