How many times you have made yourself busy just to avoid being alone? How many times have you engaged in activities you didn't like because you feared facing a Saturday night without a date or social activity?
Do you understand what you are really afraid of? Do you understand what you would be feeling about yourself or what emotion would take over if you allowed yourself to sit by yourself? Being alone and sitting in solitude are not the same thing. In aloneness you feel the absence of another, in solitude you feel the presence of yourself.
These alone moments are important in order to develop self-understanding, wisdom, values, and interests that can take you deeper into activities. They teach personal strength and help you stretch your identity. These moments build the self. They encourage hobbies and new paths for your life.
I hear too many people afraid of themselves in alone moments. They get anxious or depressed. They can't sit still without having a panic attack. They say they don't like themselves yet they do nothing to learn how much they can like themselves if they spent time staying in touch with who they really are - not what they compare themselves to when they look into the world.
People want to feel better about themselves but do nothing to learn the process of how to do that. Sit in stillness. Pay attention to what makes you happy, what doesn't, what you would like to do and what you would like to stop doing. Feel the life inside you. Try something new. Develop some interests. Learn to like yourself and what you would like in your future, then -- go there.
