I heard about it from my group of friends, they always keep talking about one piece or bleach, they would recognize masks or some stupid stuff and I kinda felt left out.
So I asked one of them if he could recommend me a few beginner anime, not some heavy stuff and long like one piece or other long anime.
Technically Death Note was the first anime I watched fully, but the one that actually got me into watching anime daily was Elfen Lied, which I watched like half a year later after Death Note.
Then I proceeded to watching more triple A titles like Shingeki no Kyojin, Clannad, Swort Art Online, etc..
Up to this day, which has been like 2.6 years, I managed to watch about 150 anime series. Im a little over the half in One Piece and I finished Bleach long time ago.
As I started watching more and more anime, I started to develop my own taste which is basically Romance + comedy or action + comedy.
