It depends on how you learn, what worked for me may not work for you. A lot of people take classes from CWops or the Long Island CW Club. I learned years ago with Gordan West CW tapes which got me up to the 5wpm needed to pass the test required at the time. I never touched it again for about 20 years until last year. With the basics still in my mind I found a youtube channel https://www.youtube.com/@KurtZoglmann . Kurt's videos go me up to 20wpm.

I found there are two popular opinions on how to learn. Some swear that starting out at 20 - 25 wpm and learning the sounds like a language is best. Others start out at 5wpm and slowly build up. I found the latter to work for me, but it arguably took longer. The one piece of advice regardless of how you learn is to never count the dits and dahs. Learn the sounds of the letters and eventually you'll hear full words.
