Our bodies operate in cycles. That’s why days exist.
Most of the time you’re doing things. Every now and then you pause to think about what you’ve done so far.
The moment you sit still is the moment old memories and feelings resurface. That happens because you’re reflecting. That’s how it’s supposed to work.
Make sure you don’t “breathe away” your thoughts and feelings. The point is to learn from them. After that, they won’t return until you need them again. Don’t avoid them.
