All the violence in videos and movies, you can't tell me that that wouldn't influence a disturbed person.
No matter what kind of challenges or difficulties or painful situations you go through in your life, we all have something deep within us that we can reach down and find the inner strength to get through them.
Bitterness and resentment only hurt one person, and it's not the person we're resenting - it's us.
In my life, there have been people that I was convinced would be around forever, and yet, somehow they managed to drift away after a couple of years. Likewise there have been people who have begun as casual acquaintances but become more important with each passing year.
Sometimes you just have to let go of the old and trust that something better is going to take its place, even if it's scary to face change and the unknown.
