A tip I learned from a maintance guy years ago when I worked at an insurance company. It works and I use this tip everytime I'm painting.
Put a teaspoon or so (normally I just pour little bit into the can) of vanilla extract (stuff used in baking). Stir into the paint (it wont change the color of your paint).
What this does is gives you the smell of vanilla as the paint goes on and as it dries.

The maintance guy would paint using this technique in the office so that it wouldnt bother any mom's to be (the smell of paint fumes) It also benefited the rest of us.
