A person is usually just as they present themselves. They are not interested in fulfilling your personal dream of their potential, no matter how compelling it may appear to you. The hope and compassion you want to show others is the hope and compassion that you need for yourself.
If you want someone else to change, your best way to do it is to work on yourself. Reach out to others who have your best interest in mind, and don't be afraid to get professional support. Yes, it is really possible to make long lasting changes, even it it isn’t as easy as hoping someone else will change. It is be so worth it!
Today, stop trying to help others at the expense of yourself. Focus on your own potential. It will lead to peace of mind and even happiness, whether or not anyone else decides to change.
