My favorite quote for sound comes from Randy Thom, who has been a lovely influence and friend in my career. He says that "it's great to be able to make mistakes when going through the period of creative discovery, but that you should try to have those things be as inexpensive as possible".
The great artists are the ones that can convey a lot with very little. Learning how to edit one’s self is one of the key core concepts of great game audio design—and, frankly, design in general. Too often, unskilled artists try to put too much into their audio design. But I can tell you from experience that working within self-imposed limits forces artists to be more creative and more decisive.
Listen to everything around you and memorize the sounds of the physical world. Always have a recorder and camera with you. Think about how and why things behave the way they do. And you better really like putting in long hours, because you're going to be putting in some really fucking long hours if you want to make sound and music for a living.
Concentrate on writing stuff that you love and people will hook into your passion. If it ever feels like a job, you’re in the wrong industry. You’ve got to love it!
I really try to do my best every time I am creating a piece of music. I try not to just be quick or sloppy. I want my music to have a high quality of construction and to have the power to move a listener. This is my ultimate desire.
Music is a gift, let the others know about it. Release it in the web and don't be afraid of it. If the music is good, the rest comes naturally. But you have to be patient and work continuously.
