This past Sunday, the Academy Award-winning actor Phillip Seymour Hoffman was found dead in his Greenwich Village apartment. He had struggled with drug addiction in the past, and last year he relapsed. He checked himself into rehab, but it is believed he died from a heroin overdose.

Hoffman was only 46 and the father of three children. He had an uncanny understanding of the world and his craft. He could take on any role and make the audience believe that he was indeed that character. We have his work as a testament of his brilliance and many interviews that always reminded us of his humility and his love for acting.

Here are 13 of PSH best quotes that reflect the brilliant star:

1. "It's hard… the job isn't difficult. Doing it well is difficult… just because you like to do something doesn't mean you have fun doing it; and I think that's true about acting."

2. "I had insecurities and fears like everybody does, and I got over it. But I was interested in the parts of me that struggled with those things.”

3. "Acting is so difficult for me that, unless the work is of a certain stature in my mind, unless I reach the expectations I have of myself, I'm unhappy. Then it's a miserable existence. I'm putting a piece of myself out there. If it doesn't do anything, I feel so ashamed. I'm afraid I'll be the kind of actor who thought he would make a difference and didn't. Right now, though, I feel like I made a little bit of difference."

4. "A lot of people describe me as chubby, which seems so easy, so first-choice. Or stocky. Fair-skinned. Tow-headed. There are so many other choices. How about dense? I mean, I’m a thick kind of guy. But I’m never described in attractive ways. I’m waiting for somebody to say I’m at least cute. But nobody has.”

5. "Vanity is something that will only get in the way of doing your best work, and ultimately if you’re truly vain you care more about your work than how you look in your work. I actually consider myself a pretty vain guy when it comes to that.”

6. "I have so much empathy for these young actors that are 19 and all of a sudden they’re beautiful and famous and rich. I’m like, ‘Oh my God, I’d be dead.'"

7. "I think you should be serious about what you do because this is it. This is the only life you’ve got.”

8. "She brought up four kids alone, and she deserves a congratulations for that. We’re at the party, ma, ya know?” – Accepting his Oscar for "Capote"

9. "I went to rehab…I don’t know, I was young, I drank too much, you know, so I stopped. You know what I mean, it’s not really complicated. I had no interest in drinking in moderation. I still don’t. just because all that time’s passed doesn’t mean maybe it was just a phase. That’s you know, that’s who I am.”

10. "I think Magnolia is one of the best films I’ve ever seen and I can say that straight and out and anybody that disagrees with me I’ll fight you to the death. I just think it is one of the greatest films I’ve ever been in and ever seen.”

11. "In 80 years, no one I’m seeing now will be alive. Hopefully, the art will remain.”

12. "There will be another film, there will be another relationship, or I'll die and then I'll be dead. But if I'm alive, I know life is going to keep throwing things at me."

13. "The thing I realized when I became a father is why parents stay and why they take off. The love you feel and the responsibilities you feel, I can see why some people go. They think, I'm never going to make this. Because it puts all of the heartbreaks you've had in your life in perspective. You're like, Oh, I thought that was a broken heart. That's been my experience. Now I'm sure there are some people whose relationships with kids are different. My kids are just, uh, they're good. They're just good kids, man.”

RIP Phillip Seymour Hoffman (July 23, 1967-February 2,2014)
