This quote means that you don’t have to constantly be showing strength, but it is important that you feel strong. Being strong does not always mean putting up a brave face and making sure to never show any weaknesses. It is more important to recognize your own strength in challenging situations and use it to help others. It also means being comfortable with being vulnerable, because sometimes that can be a sign of strength. Feeling strong means knowing that you can handle whatever life throws at you and trusting yourself to do what is right.
