Think in the gray areas.
We tend to see things in “black and white” and change is not that way.
We use expressions like “I was good” or “I was bad.” “I was on my diet.” or “I was off my diet.” “I had a great day.” or “I had a lousy day.” “Life is great.” or “Life is lousy.”
In reality, most of the time, it’s somewhere between the two extremes. When we use a more realistic portrayal of how things are, it gives us the ability to appreciate what we like while still improving what we do not.
