be doing well
1. To be healthy or feeling well, as after a period of illness. Yeah, he was in the hospital a few weeks ago, but he's doing well now. A: "How are you today, Joe?" B: "I'm doing well, thanks!"
2. To be performing well or experiencing success. A: "How's the new intern?" B: "She's doing well so far—she shows a lot of initiative." Our plan is doing well. Now we need to capitalize on our success.
