In cameras that use film, waiting for the right shot is crucial -- if you took a ton of photos, the film development fees would turn your hobby into a very expensive one! In the age of digital photography, errors you might make are totally free to delete. This gives you a chance to really experiment and take as many shots as you want. You might only get one you love, or you could end up with a whole set of usable prints. Don't be afraid to look dumb -- just take photos of anything you find interesting. Who knows? Maybe your weirdest photo turns out to be your best work yet!
