If you decide to learn it, do it as an aural 'language' with its natural rhythm & inflection. For example, B is 'DAH di' di' dit', and not 'dash dot dot dot', L is 'di DAH di' dit' not 'dot dash dot dot' etc.
Make a voice recording, repeating each letter of the alphabet several times, then random letters, then in groups. Listen to it as you drive, catch the train or whatever.
