If someone really wants you in their life, if someone really wants to be friends with you, they will make it easy for you to be (and remain) friends with them. When you have to put in so much efforts to be friends with someone, that (to me) is a sign that you’re not really valued, and maybe it’s time to find a new friend. And why spend your time with such people who behave as though they’re doing you a favor by being friends with you?
Don’t spend your time with the wrong people. Research shows that an ingredient for a long, happy and healthy life is to surround yourself with friends all the time, not just friends, but friends that are always happy. Stick close to those people who make it easy to be friends with them, and stay clear of those who frustrate your efforts to be friends with the, because life is just too damn short.
