Self-acceptance comes from meeting life's challenges vigorously. Don't numb yourself to your trials and difficulties, nor build mental walls to exclude pain from your life. You will find peace not by trying to escape your problems, but by confronting them courageously. You will find peace not in denial, but in victory.
There are realities we all share, regardless of our nationality, language, or individual tastes. As we need food, so do we need emotional nourishment: love, kindness, appreciation, and support from others. We need to understand our environment and our relationship to it. We need to fulfill certain inner hungers: the need for happiness, for peace of mind for wisdom.
In a sense, each of us is an island. In another sense, however, we are all one. For though islands appear separate, and may even be situated at great distances from one another, they are only extrusions of the same planet, Earth.
