My general advise is to take it a day/week at a time. Gauge where you're at, and how things are going from time to time. Regardless of where you start and even whether it's getting worse of better, check the derivative rates and estimate if it's doable and if you're up for how long that might take. If it doesn't work out, don't consider it a failure, or do but realize that it's how we get better or sense red flags.
Edit: when I say 'communicate' I don't mean make your point understood, we all automatically do this. The part that's hard is letting go of your own view to find some value/truth in what the other person is saying. I have trouble here too as we're usually trying to get our message out first, then get to the other understanding part but that's a deadlock.
