Recipe for a happy life

To make a happy Adult hood I think you need to learn to get over situations or bumps in the road. I say this because some people like serial killers, rapist, etc. Are hurt deep inside and that is why they take it out on other people because they are so tired and sad of their situation so they have to resort to hurting other people. I think it depends on a good child hood most of the time because when I was younger my dad walked out on me, my brother, and my mom and it was bad my mom had to take care of me and my brother. It effected me more then it did my brother because I was younger my grades were dropping I was getting in a lot of trouble but a couple years later I got over it and just said I cant do anything about it other than help out the one who stayed with me so I just started doing better in school. So yeah I think ones child hood has an effect on a persons adult hood.
