1 - Learn the basic principles (see d0m's comment).
2 - Borrow/copy like crazy from others who are better than you.
3 - Be brutally honest with yourself and know your limits. You don't need to be a brilliant designer to achieve that magical "good design" effect--you just need to get the fundamentals right and avoid mistakes. Until you develop some instincts, most of the ideas you have won't work, so you need to be willing to throw out what you've done and try again ad infinitum. If in doubt, take it out.
Last point: I think it's close to essential knowledge at this point for building viable software products. Like it or not, people judge by appearances, and good design is one of the best levers available to make people take what you're doing seriously. It's one of the top things that can take you from being perceived as a "hobby project" to being perceived as a "startup".
It's not easy to learn, but it's not really that hard either in the scheme of things, and it pays massive dividends. Even if you're using templates or paying someone else to do it, you still need to be able to distinguish the good from the bad if you want to avoid the (often subtle) mistakes that kill the perception of quality.
