One of the most important things I have learned is to live in this world, but not for this world. To point your thoughts, prayers, and actions toward Heaven, hoping that after death I will get to join the Lord. When I am able to do this, I worry a lot less about things. It is important to be responsible with this life, but worrying over what we cannot change is only hurting us further. When things change at my job, and I think something bad will happen, I can either fret about it, or go to work tomorrow and be thankful that I have another day there. And if I lost it, to trust that God will lead me to another job. To just know we can share our experiences with others, and live this life the best we can, and pray that we will be with Him. It is really all we need.
