Mind your nights
Your brain works on your last thoughts as you fall asleep, so they tend to stick
Your last thoughts before sleep leave a stronger imprint than you realize. As you drift off, your brain moves through a phase where it keeps processing whatever was on your mind, strengthening those thoughts and storing them more easily. 
Sleep research shows that the brain sorts through emotions, memories, and ideas overnight, often replaying what you focused on right before bed. Mind your nights, because your final thoughts help set the tone for the next day.
