Doing everything with one hand takes more time. You can manage this in two ways: 1. Try new things to make your routine easier; 2. Watch the time.
By watching the time you start and finish a task, you learn how to plan your day. Also, you see improvement as you practice and finish faster. This is true in the shower, too. I have a waterproof clock that hangs on a rope over the shower arm and runs on regular batteries. When I first came home from the hospital, it took me more than an hour to take a shower. Today, it takes about 20 minutes, including drying off.
