You Never Stop Learning and Improving. Rule of thumb, the older you are, the longer it may take. I started learning Morse in Boy Scouts maybe around 12 and decided I wanted to get a radio license a few years later and started doing some serious CW SWL and getting radio and electronics books from the Library and learning from them. By the time I was 15 I had taken a few old radios and TVs apart to see what the guts looked like, built a few home brew project receivers, and 2 months after my 16th birthday I passed my Novice Exam and was ready to get my home brew transmitter on the air. So I can say it took roughly 3-4 years from when I started, to getting my license exam passed for Morse. But I had to learn electronics and radio theory along with Morse, pretty much on my own, to reach my goal. 56 Years later I still am on CW and still enjoy it. TODAY, with computer programs and hand held devices and radio club classes It would take a determined adult person a lot less time.
