I was lucky and that was also the first thing I learned about programming (with the amazing 80's "The Home Computer Course" magazine). I still remember the first program I read:

    10 REM Computers are never wrong
    20 PRINT "Please type a number"
    30 INPUT A
    40 LET A = A + 1
    50 PRINT "The number you typed was"
    60 PRINT A

After a few paragraphs of explanation I learned that computers do what you tell them to do, not what you want them to do.
