This is why I'm such a fan of using NSDR, AKA Yoga Nidra, at least once a day and especially under times when you're engaging in a lot of high output ... This is a mistake many people make: They push, push, push, push, push—they're in pursuit of a goal; then they hit that point where they're exhausted. Then they start doing all the dopamine reserve pool-replenishing tools, such as Yoga Nidra or NSDR. The real key is to always tap off or refill that reservoir once a day before it's completely depleted.
