Shoot with the fine EFS 18-55mm IS kit lens that probably came with the camera.
This is also reasonable good advice. When you're ready to see what better glass can do for you -- which is to say when you can take well exposed and well composed shots -- then buy some *used* higher-end glass, so that you can sell it again at little or no loss. Use it for a bit. See what differences it makes. Don't be afraid to sell glass you've bought to try something else. It's worth going through a good number of lenses over a period of time to really get a sense of what the options are. I've been through dozens of lenses, including quite a few fairly pricey ones ($1000-$2000). Most of them I no longer own. I do own just a few lenses now that I'm likely to stick with "for good." I also know I can pick up speciality lenses on the used market if I need them for specific projects. FWIW, the lenses I've ended up with after a good period of experimenting are, unsurprisingly, f/2.8 versions of the classic 70-200 and 24-70, a 100-400, and a miscellany of alt lenses for special purposes: An OM Zuiko 21/2 for wide shots, an FD 35mm tilt-shift with an EF mount machined on by a local technician for situations where I need perspective control, an old but sharp 105mm macro originally designed for dental work, and a few inexpensive but interesting old 50mm lenses with particularly nice behaviors especially in out of focus areas.
So set yourself up to learn. Be patient. Experiment a lot. It's fun. And eventually you'll find your own stable of lenses that make sense for you.
