In whatever you do in life, always put yourself first, people ain't loyal, they will use you and dump you when you are no longer useful to them, friends will betray you when you least expected it, never rely on people to always have your back.
Do good and expect nothing back, be an angel that put smile on peoples face, God will reward you in His own way. Be independent, don't put your trust in human because at the end you will get heartbroken.
