Setting time for running of the script

Dear all,
I wonder if it is possible that we can run the script
from time to time..I meant, it should repeat the
sourcing of the script by itself? In my case, I need
to source this script manually from time to time,
like once in every 10 minutes.

emily,

while :
do
 yourscript
 sleep 600
done

Kool..

thanks,
