Human Factors
During departure from TEB with clearance for the RUUDY 4 departure procedure; HAAYS Intersection; I mistakenly started a turn towards HAAYS after passing RUUDY without receiving vectors. Shortly after the turn towards HAAYS; ATC advised about the heading mismatch. At this point I realized that I should have continued on heading 280 and expect vectors to HAAYS. ATC pointed out traffic in front of me which I reported in sight and no action was required to maintain visual separation.
M20 pilot reports turning direct to HAAYS after passing RUUDY on the RUUDY4 departure from TEB.  ATC advises him of his error.
