Decide that life is good and you are special. Decide to enjoy today. Decide that you will live life to the fullest now, no matter what. Trust that you will change what needs changing, but also decide that you're not going to put off enjoying life just because you don't have everything you want now. Steadfastly refuse to let anything steal your joy. Choose to be happy...and you will be.
When we speak our words to God with thanksgiving and release them with the faith that our requests will be granted, we put ourselves in a position to receive. God does not change and nature's laws are absolute and impartial. Thus, prayer has the potential for changing us. It connects us with God's spirit, and it is the key to His kingdom. Whatever your religious persuasion, it's a good thing to start every day with prayer.
