Lessons learned from my years of life experience include these somber thoughts.
Learn from your experiences. This prevents you from having to learn the same thing repeatedly.
Prepare yourself for the life you live.
Wherever you find yourself, learn how to live well there.
Manage your thoughts or your thoughts will manage you.
Manage your feelings or they will eat you alive.
Manage your environment. Do not be swallowed up by it.
Monitor yourself, and your behavior, always be the best you that you can be.
Monitor your actions so that they always honor God.
It is perfectly ok to be as kind to yourself as you are to your neighbor.
Do not seek revenge or bear a grudge against anyone among your people, but love your neighbor as yourself.(Leviticus 19:18, NIV)
