It'll take a while. Indeed, you will only know it has clicked when you look back, and think to yourself, hmmm, that clicked a while back, and I did not notice.
When I was learning to fly, there was this old pilot, who was just around the club all the time. While I was busy dreaming of progressing from a 150 (before the days of 152's) to a 172, I'd see him fly three or four types in a day - never needing a checkout or anything! I always wanted to be a pilot like him.
A few years back, I was flying home from work in my 150. I thought back on what I had flown solo that, and the previous days: I'd flown my 150, a Cessna Caravan, a DA42, a Lake Amphibian, and a Tiger Moth. Click. I was that old pilot, 35 years later. But the click had happened some time ago, as I was capable of flying these planes, and trusted to do so, long before I had.
I don't know when the click happened, and it does not matter really. If you think you have heard it, it was a mirage. Instead, you'll look back one day, and think to yourself, hmm, I clicked a while back, and didn't hear it. You'll just relax and smile to yourself. Ii the mean time, just enjoy....
