You choose what you believe about yourself. And it is indeed a choice.
Perceptional lenses come in two flavors. A helpful perceptual lens is empowering. It increases your options and choices, and expands your possibilities. Impeding beliefs and lenses decrease options and often result in you being stuck.
Consistently challenge your perceptional lens by asking two questions:
Is this lens impeding or helpful?
Did I choose this lens, or was imposed on me by the way I was brought up and/or past experiences?
