I think if you want this from an engineering perspective then Mark Kistler's You Can Draw in 30 Days is a good bet. It's not about how to see (unlike Drawing With the Right Side of the Brain) but if you want to draw certain types of things from your imagination, then it might do what you need and doesn't need too much equipment etc.

Ultimately if you want to be good at drawing, I suspect you have to be prepared to invest a fair amount of time - if you enjoy it won't feel like that, but if you don't then there are probably diminishing returns.
