In one sentence, describe what the following article is about: Whether you're using a new glass or one of your old favorites, it can accrue a layer of dust or dirt just sitting in storage. Make sure it's sparkly clean -- run it under soapy water and rinse it well. Allow it to adequately dry. You don't want to paint on glass that's streaky or wet. Remove any oil, dirt, soap film, or fingerprints that will mess up your paint work.  Let the glass sit to dry for about 7-10 minutes after rubbing. If you don't have rubbing alcohol, use white vinegar; it has similar cleaning properties. You want a solid 3/4" (2 cm) of your rim to be paint free. As some paint is toxic, it's important not to paint on any surface that could reach your mouth. What's more, the paint will be more likely to deteriorate if it meets drink or your lips. Make sure the tape is even. If it's not perfect, it's super easy to adjust. Use masking or painter's tape for best results.
Summary: Wash the glass well in warm, soapy water. Clean the surface of the wine or martini glass with rubbing alcohol and a paper towel. Place masking tape on the rim of your glass.

In one sentence, describe what the following article is about: Keep track of how long you can ordinarily work before getting tired. Once you have this benchmark, try working more than this on one day, followed by a day in which your work load is lighter. Periodically pushing yourself like this can help your build up to being able to work effectively for longer periods. Another technique to building up to longer periods of work is to push yourself a little further at times. When you feel like you don’t want to work any longer, or are looking for ways to procrastinate, don’t stop immediately. Instead, commit to working a little longer (20 minutes, for example), and then stopping. Getting enough rest is important to maintaining a good work ethic. If you are truly tired (and not looking to procrastinate), it is a sign that you should take a break. Whatever your work schedule is like, make sure you factor in enough time for sleep and relaxation into your day.  There is some variation from person to person, but generally adults need 7.5 to 8.5 hours of sleep per day. Work can be very important, but it is also important not to neglect other parts of your life. Everyone needs mental breaks, to have time to do things they enjoy, and to take care of non-work priorities. Maintaining a life beyond work is actually part of developing a good work ethic, so make sure you allow yourself this.  When you are off of work for the day, disconnect completely. Try not to think about pending projects, check your work email, or talk too much about work with family and friends.
Summary:
Build up to longer periods of work. Give yourself time to rest. Maintain a good work-life balance.
