Hooked on Phonics worked for me

There are certain words I have difficulty spelling. (And yes, sad that I basically write for a living)

Misspelled (oh, the irony)
Occasionally
Embarrassed
Traveled (travelled?)
Canceled (cancelled?)


Note that most of these include a double letter at some point. That tends to trip me up. Dumb blonde, much?

Ironically, I had to write the following man's name so many times last year I can practically spell it backwards: Mihaly Csikszentmihalyi. Say THAT 10 times fast.
