I've realized that although Valentine's Day can be a cheesy money-making stint to most people, it's a day of expressing love across the world. It doesn't have to only be between lovers, but by telling a friend that you care, or even an old person that they are still appreciated.

To the scientist there is the joy in pursuing truth which nearly counteracts the depressing revelations of truth.

When you're a touring musician, you're always turning over new rocks, and there's always a certain level of tension in your life. The music business, and the travel that comes with it, is stressful, challenging, redundant, exhausting, exciting, and often very depressing.

The modern artist is working with space and time, and expressing his feelings rather than illustrating.

Thanksgiving is a time when the world gets to see just how blessed and how workable the Christian system is. The emphasis is not on giving or buying, but on being thankful and expressing that appreciation to God and to one another.

Sinatra's melancholy was the melancholy of mass (old) media technology - the 'extimacy' of the records facilitated by the phonograph and the microphone, and expressing a peculiarly cosmopolitan and urban sadness.

The last time I saw Ted Kennedy was a generation after my first meeting, at the Senate subway below the Capitol on Obama's Inauguration Day. He was his usual gregarious and gracious self - with beaming smile and booming voice wishing my husband and me good luck with our pregnancy and expressing his excitement about the new president.

I'm quite British in the sense of not expressing my emotions much. I save it for my songs. If you ask about a death in the family, or a lover, I will not be emotional. I'd probably answer with a smile. Because that's what we British blokes do.

I don't really do sad, depressing songs.

'Sunset Boulevard' - the story of Hollywood movies draped on a depressing sex affair - is an uncompromising study of American decadence displaying a sad, worn, methodical beauty few films have had since the late twenties.

Poetry is a beautiful way of expressing feelings - happy, sad, angry, caring. It's also a way that we share with other people, to help them with those feelings.

I like singer-songwriters, and I find sad songs comforting rather than depressing. It makes you realise you're not alone in the world.

My dad was a homicide cop in the gay neighborhood in the city when gay neighborhoods were desperate, depressing, sad places run by the mob. The only gay people he'd met when I came out to him were corpses.

In America people get depressed for no reason. They say, 'I'm sad my boyfriend didn't call me.' I tell them, 'How would you like to spend 12 hours on a line to get bread or a chicken?' That is depressing.

If I'm trying to get into character and it's an emotional scene, I'll listen to depressing or really sad music.

I like things that start depressing and dark and end up romantic, and that's what I really loved about 'King Kong.'

What is genius but the power of expressing a new individuality?

The most pressing ethical question is to make sure that everything you do from a scientific standpoint is done for the ultimate good and positive issue for the people that you're caring about.

We are constituted so that simple acts of kindness, such as giving to charity or expressing gratitude, have a positive effect on our long-term moods. The key to the happy life, it seems, is the good life: a life with sustained relationships, challenging work, and connections to community.

I've always liked depressing music because a lot of times, listening to it when you're down can actually make you feel less depressed. Also, even though a person may have problems with depression, sometimes you can actually be kind of comfortable in that space because you know how to operate within it.

Music is one way of expressing yourself, and fashion is another.

The best, most beautiful, and most perfect way that we have of expressing a sweet concord of mind to each other is by music.

I have a passion for music, and I enjoy the process of expressing myself within the parameters of a pop song, and I don't do it to seek anybody's approval, necessarily. Obviously, you go on stage, and you enjoy it when people respond to a particular song, but the overall concept of playing music I do for myself.

When I first began choreographing, I never thought of it as choreography but as expressing feelings. Though every piece is different, they are all trying to get at certain things that are difficult to put into words. In the work, everything belongs to everything else - the music, the set, the movement and whatever is said.
