It's important to treat your best friend, romantic partner or business partner as an equal. Although your intellect is superior, that doesn't mean you are a better person. Whenever your ego starts spiralling out of control, reflect on your friend's best qualities. There is a reason you joined forces. When you show gratitude for your other half's kindness, consideration and diplomacy, you'll strengthen your bond. You'll also overcome personal shortcomings that have been holding you back. Give credit where it is due.
