No one—not even you—can be selfless and generous all the time! It’s okay to mix a few selfish acts in with your good deeds today. Don’t do anything too egomaniacal. Just put yourself first a few times when you usually wouldn’t. This isn’t an excuse to forget your manners. You should still say please and thank you, but it’s a reminder that you need to treat yourself like the star you are a little more often.
