"One of the most expensive things you could ever do is pay attention to the wrong people." - Dr. Henry Cloud

Some of us may be compliants, always conforming to the requests of others; while some of us may be the one overstepping the boundaries of others, intentionally or not. Setting up boundaries and staying firm may not be easy, but it will make you a happier, more fulfilled person in the long run.

P.S. Learn how to improve your own life tremendously when you understand the true meaning behind setting boundaries for yourself and learning how to say no, or when to say yes.
