The most valuable and important thing in your life is energy.

Not time is limited, but energy. What you give time and attention to determines your existence. Make your life a temple where only people who are able to care, listen and communicate are admitted. You don't need to save anyone. It's not your job to give your life to others because you feel sorry for them, someone feels bad because you "should". Your job is to realize that you are the master and lover of your destiny, to decide that you deserve real friendship, true commitment and full love with people who are healthy and prosperous. Then wait in silence for at least a minute... And see how quickly things start to change.
