It Takes Time
One of my clients tells me that I should have a neon sign on the wall behind me that reads, "It takes time." She says I could simply flip a switch and turn it on instead of saying those words myself, which I obviously do quite a lot ... for example, when someone asks me, "How do I learn to deal with these feelings in a better way, then?" It takes time. Any kind of meaningful growth takes a long time. I don't think I've ever had a client who liked this answer, but most of them come to accept it.
I have a friend, an accomplished tennis pro, who once told me that in order to become a highly skilled tennis player, it might take ten years of lessons. He didn't see anything unusual or objectionable about that. In order to become highly skilled at anything, you have to work hard at it for a long time. I spent four years as an undergraduate and six years in graduate school. After earning a B.S., a would-be surgeon then spends four years in medical school, followed by a long internship and residency, in order to qualify. You've probably heard about the 10,000 hour rule: it takes that many hours of practice to become expert at something.
