@Peter I remember when I was required to do some creative work at the school, inspiration helped me to some extent.

Everything influences my life. Some weeks ago I read a book about simplicity, that is/was the core value of Apple. Now, I'm trying to do some things at my work more simple, easier to undestand - I mean reports I make, emails I write. I can listen to a song and get inspired, get an idea. I can speak with a person and it can change my plans for the whole day. ...and so forth.
