Tips and Tricks for a start with Point and Shoot

Ok, I have a decent Point and Shoot. It's a Nikon S220, and I've used worse to take great photos, but am just learning this new little device, and it does take some pretty decent shots. I'm interested in tips, tricks, and advice. Here's my setup. I take it everywhere in a little belt loop carrying case that holds 3 batteries, with one battery in the camera, and I have a 4GB SD card. I have a charger, and all, but it only charges one battery at a time. The case is somewhat hard so it's protected from bumps or whatnot. I've taken some photos with it, and recently took some and will upload them when I can. I'm looking to go from this to something more DSLR/Professional and would love this as a career. Thanks!
