It's  been  three weeks now since I've started learning morse code. As
  of today, I know about 17 characters. Speed is 20  words  per  minute.
  Every  day,  I  practice for 10-30 minutes. Once I feel comfortable, I
  add more letters.

  I still use a training program I wrote by myself. It  sends  a  random
  series  of  letters  and  then  waits for your input. This means I can
  write it down on a sheet of paper -- I'm now convinced that this makes
  learning easier.
