I've learned one important lesson in my life, and I'm going to share it with you. Don't worry about bad things that haven't happened yet. It will save you a lot of anxiety.
I have spent most of my time worrying about things that have never happened. Worrying is not an action! In fact, it is action that alleviates concern and dissipates worries. Take more actions when you feel that worry is creeping in to steal your time. It need not be a huge action, any action in the direction you want to go will do.
