Boundaries are lines, they help you define what you will allow and what you will give.

Walls on the other hand keep people out of your life and prevents you from experiencing others.

But boundaries!

They take time, effort and clarity to build

But when you do, they make your life healthy and beautiful.

They become the default operating system for your life, you end up saving mental energy wondering how to deal with a situation or a person and they have a beautiful bonus too; the ability to identify red flags and smell out people who do not need to be in your life immediately. A person who has issues with your boundaries is a dangerous person. For example you make it clear to someone that you do not make or receive calls after 10pm except for emergencies, and this particular person would keep calling after 10pm, you immediately have an insight into the character of that person, you know this is not someone you want to keep around you. They will push other boundaries and eventually your relationship with them will be driven by their own needs and desires.

So start defining boundaries for different areas of your life, especially for people who tend to be people pleasers, if you want a healthy life and relationship with people, set those boundaries.
