Can be true for a lot of things, yet more so with learning, or any kind of personal development, such as health (e.g. dietary changes or fasting), and fitness changes.
We gotta keep up hope and push through a bit (within current limits), while remaining injury free. And it’s ok to take a break if the body or mind is asking for it.
Myself these days, I am needing ample downtime, alone time, and bed rest for the healing of my chronic fatigue syndrome.
I have limitations more than normal for social interactions and activity. So I apologize in advance if we cross paths and I happen to appear distant or short with anyone. It’s in the interest of my own health and well-being.
