Have a set of beliefs that you live by and live your life with an ethical and moral outlook. Never compromise those beliefs for anyone or anything. These beliefs are from your Soul, from the deepest part of you. If you do not have life beliefs or do not believe in something higher, you will literally fall for anything that people say to you. You will have no ability to discern truth from lies and will only follow your emotion in life. Following emotion will lead to chaotic decisions that may provide momentary happiness, but will inevitably lead to misery.
