As a people pleaser, it can be difficult to speak up.
First, be true to yourself. Honor yourself. When you speak up regarding a difficult issue, and you come from a place where you have already "honored yourself", you will be coming from an honest place, speaking from your heart.
Having the courage to speak up can be challenging, especially for those who may have an unconscious fear of abandonment. When we speak our personal truth, we are building intimacy with other people. We are allowing them to truly know us. We are living authentically, and we are building even more strength within ourselves.
Speaking up, speaking from your heart is an important part of Zen Living, living your own personal truth.
