Today I did a midday nap, and it felt amazing. I am not sure if because of my high intensive workouts or something else, like the autumn weather, but I am not in my lack of motivation phase and I need to take it a little bit slow.
If your body is showing you need a rest, it is better to rest than to push yourself to the limit and be unproductive and tired.
A lot of time, we are way too hard on ourselves than we should be. Another tactic is to start small. For example, if you are not used to do 20 pushups, you start with only 1 per day and every week you increase it. This will give you the resilience to continue with your goals and to progress faster than if you had just tried to push yourself.
