Some of us had awesome childhoods.
Some of us had awful childhoods.

I think for most people its a mix.

Everyone has had good experiences and bad experiences in life. The question is which experiences do you bring to mind?  Not which do you remember, but which do you bring to mind? Anything can trigger a memory - a scent, a sound, an image. Sometimes the memory is great and we smile and savor it. Other times it's not great. When one of those moments you regret pops in your head, don't wallow in it. Listen to this song. Soak in God's word about who you are in Christ.

Don't be overcome by evil, but overcome evil with good. Don't get caught in negative, evil, depressed, regretful thoughts. Bring good things to mind. Use God's word as a mirror, not your past.
