What is a good way to learn how to sing?

I've been trying to sing for years and I can't. I've been told that it comes from the diaphragm. Am I supposed to sing out like I'm whistling? With a blowing out type of pattern fluctuating my voice high and low? When I sing low I tend to need more air, is low pitch not for me or I'm not putting enough air in before I sing a note?
