Hi Lan,
Welcome to this Microsoft Project newsgroup
Yes I agree, though if you want to be up and running quickly and efficiently
you must take recognized courses in both disciplines. Learning from books is
all very well, but it takes much time and heartache as you've no one to
answer your questions except here, of course
FAQs, companion products and other useful Project information can be seen at

Hope this helps - please let us know how you get on
