Therefore, to break the cycle of bad habits, you need to reset your dopamine cycles. How? By giving yourself robust rewards. I'm not suggesting sundaes and sausages here. Instead, reward yourself weekly with shopping (it doesn't matter how little you spend, just that you have an indulgence to look forward to) or a manicure or anything that's not destructive.
As you disable the old pathways of bad habits, you'll need to nurture the new ones with new rewards. As you do, your brain will start producing brain-derived neurotrophic factor (Miracle-Gro for the brain), which increases brain plasticity to set new pathways for good, long-lasting, and healthy behaviors.
