there is nothing particularly new in this quote. I just like the way the authors say that doing at least something is good enough and move the readers away from all-or-nothing thinking.
“When you’re depressed is when you need exercise the most, but it’s also the time you least feel like doing anything. If depressed, you may not spend much time moving at all, but the goal is to start by adding a little every day. It may feel like a workout just to get out of bed in the morning, but making it a habit like brushing your teeth will make it easier for you to maintain a program of activity, no matter how depressed you are. You may have been more active before your depression, but doing something is better than nothing. It may be very difficult to start moving, but it will ultimately improve your mood and make you healthier as it boosts your immune system, which gets weakened by depression. Even when sitting on the couch, you can do leg raises, or you can walk the hallway of your apartment or home, or the stairs in your building if you do not want to face the world. Whatever exercise you do, it’s better than just sitting or lying there.”
