Practicing gratitude and being thankful can lead to greater success in just about every area of your life.
Researchers have found that gratitude impacts physical and mental health, correlating to lower blood pressure and heart rate and even better sleep quality. Other studies have found that gratitude builds stronger relationships and emotional well-being.
You can spend 40 seconds a day being consciously thankful and grateful. At a certain point, that thankfulness will start to become second nature—your brain can be rewired to find the positive in every situation and with less conscious work on your part.
Granted, it’s much easier to be positive when everything feels and is going great. The challenge is to figure out how to be grateful when things feel horrible and then train your brain to find that the positive in every situation.
