It's your unlimited power to care and to love that can make the biggest difference in the quality of your life.
Some of the biggest challenges in relationships come from the fact that most people enter a relationship in order to get something: they're trying to find someone who's going to make them feel good. In reality, the only way a relationship will last is if you see your relationship as a place that you go to give, and not a place that you go to take.
Only those who have learned the power of sincere and selfless contribution experience life's deepest joy: true fulfillment.
