Make these three things a habit:
1. Pace yourself. Switch between heavy, hard, or repetitive tasks and light or easy tasks. Make sure you take breaks.
2. Be kind to your joints. Put as little stress on them as possible. Use larger, stronger joints when you can, instead of smaller ones. For example, wear a shoulder bag rather than a handheld purse.
3. Get an assist. Many helpful devices -- like canes, grab bars, extra-thick pens, luggage carts, or sit/stand stools -- can make your day easier. Ask an occupational therapist which ones would help you.
