I totally agree.  Practice may not make perfect, but it will make better.
I'm aware of extraordinary pressure on parish priests in terms of their time.  I have a friend -- a life-long friend: we met in first grade -- who has been a priest for more that forty years. He tells me that he no longer has the time to simply sit with sick parishioners, as he used to do. If I didn't know him so well, I might be tempted to ask a snarky question, such as, "What are you doing that is more important than sitting with Mrs. Jones?"  But I'm sure he would tell me that there is nothing more important than sitting with her -- but many things and many people just as important. He's pastor of three parishes -- not what he signed on for, not what he envisioned for himself at this point in his life. I try not to jump to conclusions.
However, all of that just goes to underscore the importance delegating and sharing ministry. Priests can't do it all; we shouldn't expect them to; we shouldn't want them to.
