So the best thing is to really work on yourself and opening your own heart and just letting all that stuff [worrying] go. And it is possible. It's sometimes takes a lot of time; it's not easy. And a lot of sitting with yourself and trying to work with your own heart.
If a problem is fixable, if a situation is such that you can do something about it, then there is no need to worry. If it's not fixable, then there is no help in worrying. There is no benefit in worrying whatsoever.
The fact that I am interrupting serious work to answer these questions proves that I am so stupid that I should be penalized severely. I will be. Don't worry.
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.
