Seriously expect the worst in people, and expect yourself to bridge the gap to make things better

One must come to a point where they take up the pack upon their back and have the responsibility to take things into their own hands

Its similar to what Dave Ramsey said that as parents, we should raise good ADULTS, not good children. we should not care about their GPA but reward and punish them based on their character and how they treat and respect other people.

If someone close to you in your life wants to be a piece of shit (it may or may not surprise you if they have done this already so any times in the past that you're already basically emotionally numb to it because of your expectations have crashed into oblivion several times before), focus on what YOU can do about it and RESPOND to the situation instead of reacting to it.

Realize the breath of life that you can breath into situations to make things better and how you have to pull yourself up by the boot straps and the entire situation. Raise the ocean so that all the boats in the water rise.
