Do you end up in a knot yourself trying to knot a tie? There are so many ways to tie a tie (something like 79) that one could almost tie any kind of a knot and approximate one of those ways. However, if you want to make it look right, then easy knots to learn are the Four-in-hand, the Half Windsor, and, for wide (cut away) collars and formal occasions, the Full Windsor. These will see you through most social and business occasions.
