For some reason some beginners seem to find recursion a natural pattern.

Many others, including quite experienced programmers find it a mind
bending concept.
But as a general rule, where you want to repeat an naction a number of 
times thing loops. If you know in advance how many times to repeat (eg 
all the items in a list) think 'for' loops, if you don't know how often 
(eg until some input condition is met) think 'while' loops.
