I’m sure you’ve heard “When life hands you lemons, make lemonade.” The question really comes down to: How do you make something sour or bitter into something you enjoy?
What words are you telling yourself? What music are you listening to? What you think about is what you bring about.
Example: When you have to be around someone who you don’t get along with, are you telling yourself, “I can’t stand this person” or “I can manage being civil to this person for a little while”? Make it manageable.
