Not easy to do, but life would be a hell of a lot easier if we could take nothing personally.
Whether it’s a family member saying something hurtful, or a partner appearing distracted, or a prospective employer rejecting you from a job, it is almost always because of their own issues or problems. For example, the employer might want a male to equal out the office dynamics, or the partner might be stressed because of problems at work.
It is important to remember that often it is not all about you. People have their own personal or professional issues to deal with and it should not lessen your self-worth or self-esteem.
If you can remember this, you will experience a great sense of freedom.
