The only good human being is a dead one.
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.
Most people never feel secure because they are always worried that they will lose their job, lose the money they already have, lose their spouse, lose their health, and so on. The only true security in life comes from knowing that every single day you are improving yourself in some way, that you are increasing the caliber of who you are and that you are valuable to your company, your friends, and your family.
