Bad karma refers to a series of negative events and consequences that occur from bad choices and poor decisions that an individual makes. If you spend your life being selfish and self centered then you should not be surprised when you are unlucky. Reaping what you sow is a spiritual concept that means if you do good then good will happen to you, but if you do bad things that harm others you will end up having negative events and unfavorable consequences in your future as well.
Family isn't always blood. It's the people in your life who want you in theirs. The ones who accept you for who you are. The ones who would do anything to see you smile, and who love you no matter what.
