Step 1: Start with a fresh face. Wash your face with your favorite cleanser, pat dry, then apply moisturizer.

Step 2: Apply a liquid foundation to your face using your fingers. My guess is that if you are literally just starting out in makeup, you don't have a bunch of makeup brushes lying around. Even though I have more than enough makeup brushes, I tend to use my fingers to apply my liquid foundation when I'm going for a natural, everyday look. The great thing about liquid foundation is that it isn't too heavy, and if you find that it's giving you more coverage than you would like, just add a drop of moisturizer to thin it out.

Step 3: Use these three products to make your face look refreshed: mascara, blush, and gloss. Mascara helps to frame your eyes and bring them out. Blush gives some color/warmth to your face, and gloss gives you that pop. To go a step further I would do bronzer either instead of or with the blush, or use MACs Mineralize Skinfinish in Natural. This helps give your skin a natural sunkissed glow.

Here's a tip: Cream blush can be a two for the price of one deal. Left your lipgloss at home and at a lost as to what to do? You can apply your cream blush to your lips to give them a little color and pop.
Another tip: Some days I feel like I just have to have some color on my eyes even if it's just one. Blush is wonderful for a little pop of color on your eyes. Just sweep the color over your lids and voila!
